LED Turn Signals and Hyperflashing - Resistors vs. Relay 

Being a retired mechanic, I use to take the front seat out and then lay on your back to get under the dash. Pain in the A$$ but some times works .

I recently converted my 96 Tacoma over to led and did the flasher relay and it was a plug and play. I tore my dash apart and pulled the fuse block to get to the flasher which was located on the back of the fuse block. After a few choice words I got the dash all put back together and while I was making sure I put everything back together correctly, I found out that I could have reached up behind the fuse block and pulled the flasher out that way! Oh well you live and you learn!

Hey. Pro tip: always keep a little kid like a 12-15 yo boy that is smaller and can get under the dash. I use my son all the time to help with stuff like that.

This is like watching Scotty Kilmer with the opening of the video. Hahaha.

Fine job and entertaining also. Toward end I figured you were going to snip off the the sockets and switch them out...glad JDM will make resistors for them now. Good luck!

Couldn't agree more with you. And for some reason even to this day the regular Prius STILL has incandescent turn signals and so does the Nissan LEAF and Chevy bolt EV. However the Prius Prime finally has stock LED amber turn signals. Let's hope all hybrids and EVs come with that soon

Good information Thanks

In my Ford Expedition, I literally just had to stick my hand up the back of the dash, flip a cover off and rip the relay out, these engineers should place relays more conveniently for the inevitable moment when you need to replace one... :)

I spent over $2000 with Jdm A Star they never made any special harnesses for my vehicle for a 2014 Subaru outback And I believe the owners name is Kevin

If it makes you feel better, I repaced the EL-12 flasher units on my car, (one for the indicators and one for the flashers) with special LED flasher units, and it didn't work, so I will have to go to load resistors. Secondly, you should only need ONE load resistor for each side of your car, not one for the front and another for the back, BUT all cars seem to be different in this area, so YMMV.

nice vid. Thnx. 👍

HandyDadTV you can look on Amazon for Luyed Led that is plug and play, no hyper flashing. I replaced all 4 on my car

In my old Toyota Corolla 1991 ... just changed my old Flasher Relay to a LED Flasher ... cheaper / simpler ... than installing Load Resistor ... my electrical consumption is even lower than before ...

After this vid i need a beer

I'll give it back... OMG that just made my day lol

awesome video! loving the LED videos

I like your video it’s funny and informative

You might like to know that I put LEDs in my rear tail lights for my 2016 Ram 2500 and although I get the hyperflash indication in my dash, I do not get the fast blinking in the tail lights. It blinks at the normal factory blink rate. But the turn signal LED markers on my side mirrors hyperflash at a faster rate than normal. If that isn't weird

I wounder If buying a repair manual from internet for the owned car have all repair from the major repairs to the little one like lamps & accessories to save time & not breaking anything?!

Lasfit makes ones that have the resistor built into the light. No relays, no in lines, just plug and play.

You r just like me I'm a big guy too and I have been going crazy trying to find a high enough watts led bulb because my 2021 forester has 28 watts . So I'm got the front working great because I have resistors in the front but my back r the problem. Cause I don't have enough room to put a resistors case they r outside on the corner its a pain in the but. I'm going to try to l Find my flasher under the dash.

Big guy here, 2005 Honda Pilot.... I gave up... went the resistor route. Cut and splice method. Aftermarket replacement sockets would not fit.

Where did u get the relay? I would like to try the relay vs. resistors......

Does hyper flash damage anything ? Like mess with any ecu's or relays or other elactrical parts? I'm guessing it may burn out the turn signal led bulb slightly faster? I have an 08 prius and I don't mind the hyperflash. I'd like to avoid hot resistors and keep the led power savings.

I had a same problem when I tried to unplug the cable from an old relay (2007 Sienna)... I gave up..

You lost when you bought a Prius! Lol! 😆

I recently bought front LED signal housing for my civic model 92-95. By manufacturer, when start the engine, the signal light turn ON solid. When headlight turn ON, led signal didn't fully OFF then ON. It dim a little and blink...very hard to notice on bright day light. If headlight is OFF.. the LED light blink like normal. The LED signal housing comes with LED resistor pre-assemble. Do u think I need to replace the OEM signal relay with the LED relay?

As always, nice video!

One funny DIYer! This was like using a banana for a turn signal lol! :)

whats your turn signal relay model just curious

Well def not resistor vs relay , didn’t get to see the relay work. Rename to you vs Toyota! I have these huge resistors on my mustang signal bulbs and the headlights won’t fit properly back in their slot with the resistors, they also switch backs so it takes a full second or more to go back to white after using the signal, would relay fix that ?. Was wondering too if I have resistors in the tail light led already can I use the relay for front and it won’t affect them?

the best solution is to get a turn signal wire kit split 2 way or 2 of them or 4 way with electronic led flasher relay up 240 watts and fuse to connect direct to battery and then on to turn signal light's then purchase led light bulbs with fans or self heat dessipate the ones that dont need electronic relay nor resistors,, ,they still get hot,, if you can disconnect relay on car and or fuse,, some come attach to emergency lights, that is the best way cuase leds get real hot , relays for low current that fitare hard to find on some vehicles

one question , will it matter which way you pug in those original tall parking / stop bulbs like a 3057. I often wondered why they have 4 wire contacts on them but they are staggered .

i hope u are my dad as my late dad..because we share a same hobby..hahaha

3:08: Not with a Saturn you can't. They're built in the Warning Flasher button. You'll have to use the Resistor method with these.

despite watching you give up I just told the dealership I'd replace my own relay... just couldn't stomach the quote for labor to replace such a small part

Chief simple way is to get the main wire to extra bulb holder that from there get the current directly to led bulb holder rather than get high price resistor . What you need is extra bulb holder and normal bulb paint black thats it

pro tip...the cars owner manual tells you where the relay / fuse box is located 👍

It's 2 to 4 screws to take off the bottom cover under the steering wheel...and maybe 4 more for the bracket...work smarter not harder

Hyper flashing is basically a current signal sent back that says a bulb is out. If all the regular incandescent bulbs were left i and one went bad it would hyper flash. The less wattage with the LED simulates a bulb out. The aftermarket inline resistor boosts the wattage back where it was. Now the only benefit will be the bulb will last a lot longer however your saving no power. I just had a nightmare myself. Turns out my 2011 Ford E350 has no flasher relay it has a programmable box to adjust the wattage as needed. Has to be done by the dealer special codes. Resistors get red hot even when mounted so I switched back lost about $30 and a few hours and got over it. At least for my van. Next one I buy will have them already. Oh no I have two 72 Cutlass's I know they have a flasher relay I think here we go again

Same issue with my car but what I need to do please help to sort out tnx …

i dont get how the 50w resistor (+ at least 5W LED) is supposed to immitate 21W wolfram bulb. shouldn't it be like 20W resistor? why so much resistance is needed?

Bad advice . Just to the right thing and get the flasher out . I got those resister type put one in and removed after feeling how hot it got

Since you put the resisters in the front,can't you live with a slightly quicker flash with LEDs in back too,without?

Do they make inline resistors just like this one for my 07 Dodge Ram 1500? Google wasn’t to friendly

Why not cut your normal socket and wired to the resistor????

Why not cut off each socket, flip flop them and reattach?

love your vids. Vleds.com have resistors that you can tap into your wiring, or if you get their Triton series, plug in. Warning: Tritons are EXPENSIVE, but well worth it, trust me.

You remind me of Alton Brown automotive version though lol

My mom has cool white led lights for turn signals

ok so... I have the regular filament bulbs on my signals, Then I changed my flasher relay cuz the original one burnt out, So why am I getting hyper flashing when Im not even using LED bulbs for my signals? What can I do to fix it?

So my right turn signal is hyper flashing.... my left one is fine and my hazards are fine... front and rear bulb aren't out sooo what gives?

Funny S#it!!!! Well done!

Great resistor doesn't work and I can't change the flasher on my Leaf ffs

Where did you buy the LED turn relay??

Did the bulbs get dimmer and produced less light after the resistor or it's only me. To me it looked dimmer. compare the output @ 2:00 to the output @3:50

Cut the sockets off and solder the car socket to the resistor wires... the end. Oh, you could have went to an autozone and asked them where that flasher is located on your car or just have them show it to you while you were there. It just might be under the hood.

Just for shits and giggles, maybe a look in the owner's manual would have helped locate the flasher location. Or a trip over to the Priuschat forum for a bunch of information on this vehicle. It does look like you are having fun though, so carry on. A lot of people wouldn't even think about trying to do something on their own with their car let alone actually getting under the dash. I feel for you on the "big guy under the dash" syndrome as I have personal experience being upside down with the driver's seat fully to the rear and my legs where my upper torso normally sits.

Surprised a Prius owner even knows what a turn signal is.

Actually I think hyper flashing is more noticeable to others at night than the standard flashing rate is.

I thought we were watching the incredible movie

Hey man I watched ur video last night n I would love to speak with you, ASAP PLEASE !!!!

Not all cars will accept the fix of using only the led flasher. Ask me how i know..

Replacing a relay seems like it would be way more expensive and complicated

So basicly this video was useless

Cocaine is hellavu drug lol

just leave the hyperflash so ppl know ur in a rush!

I just bought the Smarttap relay from diodedynamics lol, much easier, or well... the relay is a bitch to install, but still lol.

Or lay of cheese burgers lol

What mods could possibly be done to a Prius! WTF

I hate Toyota.
