How to Fix Hyperblinking! Installing Resistors for LED Turn Signals | Diode Dynamics 

Thanks for actually showing putting the wires into the clip. Every other video I have watched goes away, and comes back with "and it's that simple."

Wouldn't it make more sense to build the resistors into the bulbs?

As easy as the installation is, you have explained it the best, very clear and concise instruction with a very clear video view. Many thanks.

This is the only clear installation instruction on how to install those resistor splice connectors. Well done. But in my search I also discovered that instead of using in line resistors like this one can often modify the flasher relay to eliminate the hyper-blink. I would suggest looking into modifying the relay for your particular car instead of putting resistors on all four corners. Good luck.

Just want to say I just fixed my hyper blinking bulbs following these directions. Thank you!

I installed the resistors today on my front led turn signals & now my front and rear signals work perfectly " Thanks Paul for the help..

Worked Perfect for my car, put the turn signal back to normal blinking pattern! great product and highly recommend!

Thanks for the video, it helped alot. I used 50W, 6ohm load resistors for a 97 grand am and my turn signals work great. For quick install tips: 1. blue - power, black - ground 2. back and front load resistors must be installed for one side to work properly. Both sides must be installed before all 4 turn signals are working properly. 3. back turn signals - yellow - power, black - ground. Hope this helps,

I've been looking for a short video like this that explains how to use these resistors so I could switch to LED turn signals, but had not found one that showed or explained it as well as yours. I now feel comfortable in making the change myself. Thank you very much. Can I recommend or in some way attach this video to the Kia Optima Forum so that others might benefit?

Best video I’ve seen that goes into detail for installing a resistor. Great job man.

I appreciated the video man I had no idea how to install these things, even with an electrical technical support background. Good job.

Just did this to my 1996 Mercedes G320 with 50W resistors, works like a charm, thanks!

I just install my 1157 LOAD RESISTORS 50w 6OHM. It was real easy. After installing it, I had a bit of a problem. It was still hyper-bliking. I took some steps back and made sure everything was properly connected. I then "Re-Pinch" the "Slice" all the way down )it was half way in). Then it worked like a champ. You must pinch the slice all the way down!!! (Flush) for it to work!!! Thanks again. DIY video for resistors.

Best video I found on the resistor installation, especially since I have the exact same kind of wires.. I was getting confused with other other videos because they had more than 2 or they didn't show it in more detail. Thank you!

Straight to the point awesome!

For vehicles with a flasher relay, it's MUCH easier to just replace it with an ADJUSTABLE RATE FLASHER. Maintains lower current draw and adjustable rate knob is very nice!

Great Video!!! Do i have to put a resistor on each led turnsignal or is just 1 enough ?

I just installed new LED tail light assemblies on my truck. But now I'm hyperflashing and have no running lights. Do I use four resistors and splice into both my turn signal and brake or just use two resistors and splice into one of the two?

Thank you for this video ! all the adverts for these resistors were stating a connection in series !! I was trying to work out why it wouldn't be parallel but you've just confirmed my expectation ;0) .. Cheers ..

I was wondering if you’ve had a scenario where one side blinks fast while the other is normal after installing the resistors? After installing a resistor on each bulb, one side blinks fast except when swapping out the LED at either the front or rear for an incandescent bulb. Great video.

cengeb, very interesting detail to point out. I also seem to worry about things such as this when doing mods to my vehicles. Question, has this stopped you from using these bulb in your vehicle? For me cost is a factor in some of the replacements. Thanks for your input.

If you only do this with the rear(replacing with LED's) Can you have regular incandescent bulbs in the front or do you need to do leds on all signal lights?

"Solder if you can", were my exact words. I can (very well) so I did. Cracking is due to a "cold solder", like you said is a poor job. But minimal tools can give a solder joint that will last indefinitely. But like you said, again, you have to know how.

That was easy, any ideas on how to mount the resistor on metal? I dont want to be drilling holes throughout my car

Awesome and very helpful video,thank you.

Thanks for instructions, however i have similar resistors but with 2 wires on each end of resistor, do both wires do same thing , ie can i use for stop/ tail light elements ??.

Good video! I bought 4 led bulbs for brake likes, and I don't what ohm or watt resistor to use. It plugs into 12v and uses 10w. What resistor do I need? Thank you in advance for your feedback.

Awesome! Would this same theory work for an interior (home) 12v light fixture? I changed all the bulbs to LED from halogen and the "flicker" unless I put one halogen bulb back in with the group to increase the load. I have to use at least a 20w bulb otherwise it will still flicker with a 5 or 10w. They are small bi-pin bulbs and I was thinking I could just put a resistor along side one of the bulbs to increase the load. But how do I know what resistor value I need?

Hi. This is a great video. Just one simple question though. What happens if you just leave it hyperblinking? I like it the way it is as I customize my car a lot. Thanks

thanks for the help. you made my install alot easier!!

Was wondering, do they stay hot or only when turn signal is being used? Are they too hot to put a zip tie around? Installing them on a 2013 Nissan altima and was curious so I know where to put them. Thanks my fellow RU-vidrs

I got a pair of led turn signals for my Sienna from you guys. Good video, and I have the exact same issue, I think I will need to get 2 pairs of resistors from you guys as well. The only issue I have at this point: I installed the LED signals, turned them on, got the hyperblinking, turned them off, switched back to stock halogens until I get the resistors, and now my turn signals or emergency lights dont come on. I also dont hear the clicking noise from the flasher by the steering column. Could it be that it's the fuse that burned out or the flasher box needs a replacement? Please help. Thank you.

I spliced my cables however, while splicing, one of the quick connector clips (the clip that goes over the metal piece used to splice) broke and it's only the t-tap without the secure clip. I made sure that the connection was secure and put electrical tape around it so that the connection remains secure, but I'm just wondering if that will last. I'm worried that it will lose connection because of the broken off clip. Thanks!

How did you mount your resistors? Could double sided tape work, or zipties?

Thanks for the helpful guide!

Thanks for this helpful video, but could you tell me the differences between 25w 6ohm and 50w 10ohm resistors?

Paul, Please Would You Tell Us What Res. To Use? No One Has Yet Told Us What Type Res. To Use? Thanks, WW

You said it is OK to mount to hard plastic. Please confirm that as every other video says mount only to metal. Thank you, good video.

thank you very much for your information I will take that in consideration but in the meantime I also found that the tail lights do not come on so I'm wondering if it is a fuse that's the culprit

i have a 2009 ford fusion so i can buy the led brake light and install it . or i will have too buy a reseistore too.it is brake light and tun signal too. can you let me know

Do you have to do this for each blinker? Front, Rear, and fender? on both sides of the car? So six times?

Say I do this and install LEDs in all my lights. Would i be able to use non-LED later without unsplicing everything? Or does LED last long enough that it wouldn't be an issue? Thanks

Do you have to install a resistors on each side (front L+R)? Or just 1 side.

Will this also work if the LED turns on but don't blink when using the turn signals? And the LEDS turn on as soon as I plug them in even though the lights are off.

Must've been reading my mind because I surely needed help with installing load resistors on my altima. I just need to know which wire is my turn/parking light

I am installing load resistors for my Toyota Tacoma. It will be the front signals so I have to put them in under the hood somewhere. What happens if they get wet during the rain?

I want to replace my halogen bulbs with LEDs on my 1980 motorcycle. What type of resistors and bulbs should I get? I also live in Canada Look forward to your answer as I also want to install fog lights that also replacing the halogens on them also..All are H4 and I have not yet investigated what the markers bases are for those lights to replkace. Thanks! Age

So am I correct in assuming that for EVERY bulb that blinks you will need a resistor if it is converted to LED? I have a 16 Fiesta ST and am insterested in going all LED but I would need 6 resistors for all the blinkers it has including the mirrors. Any help is appreciated, thanks.

do you got to put a resistor on each LED bulb? Or just one for front and back LEDs or one for front and another on the back?

Do I need two resistor kits if I decide to replace both front and rear turning signal? Or just one kit will do the job for the entire circuit? Thank you

excellent video and description. well done!

Hey man, I just attempted to install 50w 6ohm resistors for LED turn signals on a 2013 Honda Accord Touring. I followed your steps and unfortunately I am still experiencing hyper blink. I used one for each bulb as well. I need assistance. Thanks!

Why is the resistor 50W when the bulb is less than 25W? Could the job be done with a 25W resistor, and be cooler?

ahhh man that looked so easy but I'm sure I would mess that up - I want to order some Switchback turn signals for my 14 Altima - they even did a video on Switchbacks on my car

Worked great, thanks for the explanation!

Please make a video how to install the led resistor on golf mk6 tail lights because the wiring is confusing. Thx

I am looking to install LED front blinkers on my 2001 Triumph 600tt.I would also like to avoid the hyperblinking. Would this help me avoid that on motorcycles as well?

Will this work on a sequential light strip? I bought a 24 inch and trim it down to 4inch the light look solid now because lighy is traveling to fast.

This might be an obvious question but im just checking; Does the more Ohm's the resistor mean slower blink rate?

does one load resistor do the entire circuit? I've got the hyper flashing problem with resistors on the way, but I also have LED side indicators near the front doors I'm putting in and was wondering if they will also hyperflash

My new bumper doesn’t have fog lights, what do i need to make it think the ecu theres bulbs ? As im getting error on cluster and I don’t want to put a bulb? What do i need? Thanks

Hello there, I have a 2000 chevy silverado LS 1500 and can't seem to figure out which wire is which. The socket or fitment has 3 wires and from what I can see it has a blue wire and two black ones. Any idea on which wire I would connect the resistor to? Thanks

Quick question, how do you guys shield off the resistors from any other wiring and items in its surroundings. I know resistors tend to get hot, and almost no one explains or shares any techniques on how to properly shield off these resistors :(

THANKS A LOT GUYS VERY GOOD INFORMATION, WELL DONE.

So I got these and put them on my 2005 Pontiac Grand Prix. I put new front turn signal led bulbs before I got the resistors. After putting the resistors it still hyper links. I spliced the blue wire, as the resistor video showed most cars have red but in some the turn signal wire is blue. I spliced the blue wire with the red from the resistor kit. I also spliced the black wire as was stated in the video with the other red wire from the resistor kit. So did I do anything wrong because it still is hyper blinking. I would appreciate it if diode dynamics would respond.

im guessing the black wire is my ground but I don't know which of the other 2 wires are for the blinker and for the taillight/breaklight

@funnymanseven, if you have a dual filament bulb as your turn signal (7443) then use a test light to determine which is your blinking wire, either that or your resistors aren't enough or not making good contact

Those LEDs are very bright. Are the Stage 2 Switchbacks that bright?

Awesome vid man helped me alot

And this resistor can affect the original brightness of the bulb??, regards and thanks.

I am wanting to upgrade my turn signals in my 95 civic sedan to led when I installed them They did as shown in the video but I only had the front installed when I did the rear the turn signal buzzed so I installed an electronic flasher and I blew some fuses when I tried to use the turn signals will the resistors fix my issue with this project

Paul I replaced the flasher when I replaced the whole rear light s its worked good until now. the flasher blinks all the time even if you use no key also with no key the signal lights will work with the switch I have ordered resisters will they fix the problem ?

Hi here. Great Video and informative. BUT. I have a Skoda Octavia Facelift 2012 MK2 1.8 TSi DSG. I am in the UK, so it is BRITISH specification. I have installed LED PY21W bulbs for my Indicators ( Direction flashers to you in the USA ), and W5W front marker ( side ) lights, but when I start the engine, they all flicker for about a second, but in use I do not get any hyperflash, or dashboard warning.. I think the flicker is the onboard ECU testing the bulbs on start up. Because of this, I am holding off doing all of the other lights like the marker ( Side ) lights and the stop/tail ( P21/4w ), etc. I also want to avoid the dashboard "BULB OUT" warning light. I would really appreciate a brief tutorial, or advice on what to do. Should I just put the same resistor on every circuit., even the 5 watt marker lights. And what value resistors do I need for 5 Watt marker lights and 21 watt Stop lights ( P21/4w ) and 21 watt (P21W) fog lights, and 21 watt P21W) Day Running Lights + 21 watt (P21W) reversing lights, whilst still keeping the extra brilliance of the LED bulbs, but getting rid of the flicker on start up, and the dash warning light. Many thanks in advance, as I know this is a big ask. Keith.

I bought some LED tail lights for a 13 GMC Sierra upon installing them I had the hyper blink but they were plug and play it had a resistor already in them you tell me what problem I have?

This video was a lot of help. Thanks

So I bought some led light tube/strip that works as lights as well as signal. It has this problem too, do you think getting some resistors would fix this problem for the tubes I bought as well? Thanks

Does matter where we put each cable coming from the resistor? Is one side neg- and one side pos+ on the resistor?

I added some 33watt 3000 lumens led bulbs for my headlights on my Jeep Patriot. Will this resistors stop my flickering

The "bench test" indicates that they should be about the same brightness. However, we won't be sure until we install and take exact comparison photos. Thanks! -Paul

Does it matter which way round the resistor is connected? As I can't see any positive or negative markings on my resistors. Cheers

If I install LEDs on my front and rear blinkers do you need a resistor on all four blinkers (front AND back)? I read somewhere that one resistor on each side is enough, but I don't know if that's true.

I have 2007 chevy silverado and replaced both headlights and Tail lights with leds, just 3 weeks ago and now it's blinking fast with no bulbs out, do I need a resistor and if so why didn't I need one before, also what kind do I need.. SPYDER halos and leds .?

I take the blinker on my chevy s10 open it and add resistance on the spring they work awsome ;-)

Do these cause electrical problems down the road? I was advised moisture may set in the lines and cause some electrical issues.,

I bought blinkers from aliexpress but they are super bright. Is there a way to dim them using resistors?

So you just have 2 wires together, and tap, dont need to cut the rubber cover from the resistor out?

I liked the hyper blink over the slower blink...

I just finished completely rewiring my 1948 Willy's Jeep. Upgraded stop, tail and turn lights to LED with new electronic flasher. Installed a turn signal switch by Grote to integrate turn and brake light functions. Charged the battery to 12.6 volts. Now when I test, all systems work fine when operated individually. Also, Brake light works together with either head/tail lights, or when turn lights are on. Problem is, turn lights will not operate when head/tail lights are on at the same time. If the turn signals are on, and I turn on the tail lights, then the turn signals stop. If the tail lights are on, then the turn signals simply will not come on. I have confirmed that each light fixture is wired correctly. The head/tail light circuit is completely separate from the turn and brake light circuits (different fuses and wires). From reading the posts below, the electronic flasher should allow the system to work without wiring in load resistors. Any ideas? Thanks.

When adding an led strip to your turning signal lights, is there a way to make it so the added led light act as ONLY running lights and not act as a sequence turning signal?

How do I know what wattage resistor to buy? Where can I find it in my owner's manual?

Hi Paul, I installed LED tail lights in my '95 Mitsubishi GTO (3000GT) and used the same resistors as in your video. My left side works normally, but my right doesn't and I am not sure why that is. I do get the hyperflashing, but not 100% of the time. Sometimes the turning signal operates properly and other times it doesn't. For example, when I turn the right blinker on, it flashes normally, but when I hit the brakes at the same time, it starts hyperflashing. Also, sometimes it will hyperflash at all times, even without the brakes being depressed at the same time. I thought that the resistor was defective so I replaced it with a new one, but nothing changed. I don't see any problems with the wires so I am very confused. I even changed the front right blinker bulb, but that didn't change anything either. What could be the culprit? Thanks in advance!

So I installed LED Brake/Blinker lights in my 2017 Grand Cherokee. Inside the car it's hyper blinking but my turn signal outside blinks normal speed. Any idea what this means?

For a full size vehicle does it require 4 of these resistors for all four blinkers?

Since I am leaning toward allowing my LEDs to hyper-flash I did some research. It appears that fast flashing is a good thing. A 1975 study by David V. Post for the National Highway Traffic Safety Admin says "high flash frequencies and minimum flash duration should provide the best conspicuity and smallest response times." Easier to see and gets faster response from the drivers that need see and respond to them. Not trying to sway anyone, just thought it was interesting.

I tried to connect a resistor to my Audi TT. But they have two bulbs powered by one wire. Connecting a resister to the one still had my blinkers running too fast. Does each bulb need it's own resistor?? Cheer.

Where did you get the bulbs? Often, poorly-designed knockoff bulbs don't have any switchback function actually built in, and they work like that.

Can you wire in a 194 bulb and it do the same thing?

And what will happen if you leave it without resistors, is bad for the electrical system?? This quick blinking affect the led bulbs??

Do I have to put resisters on break lights or the reverse lights I have 2002 Dodge Caravan se

If I install LEDs for front DRL/turn signals and install load resistors, will I need to install a second set for rear LED turn signals as well?
