Dimly Lit LED Problem Fix 

Right on!!! good work.

Bradley Macaulay did it work for all interior lights or only for the light with the resistor?

thisizdavid Definitely.

josh33025 I did the same with 2008 Mustang and I get a little glow while power if off.

Did you do it? And did it work? How did you wire the resistor in?

@@newfie-dean5803 yeah I just put the resistor in with the bulb when I install them in the socket. You need to bend them so that one end goes to the positive and the other goes to the negative side. Just be sure the positive side won't touch ground, trim them shorter if need be.

@@josh33025ok, so the resistor itself hangs outside the socket? Dues it get hot? I think only a 100 ohm is needed and won’t get as hot. I used LEDs for years with no problems in a 2006 mustang GT. However the map lights and license plate light would flicker after a while so I changed them a few times. Also sometimes part of my tachometer lights would go out on the instrument cluster. I’m pretty sure this is all related to the lights and the BCM that controls it all. This summer I purchased some expensive VLEDS V6 extremes for the tail lights that are high quality: I also changed the license plate bulb and the map lights to VLEDS. Since then the tachometer light usually lights up always but what happens now is after driving the car for an hour or so it turns off the license plate bulb and two of the rear park lights, one on each side, the lights closest to the trunk badge. I tried other bulb brands like Sylvania and Diode Dynamics with the same issue remaining. When the lights go off if I flick the switch on and off everything works again. I have been told a 100 ohm resistor should fix this: I think if I bought CANBUS bulbs for the license plate and the map lights it might fix all the issues including the tachometer light issue.

Johnny Chan You should only need 1 resistor.

DIY: Car Modz Just added a resistor to my led and It *greatly* affected the brightness of my leds and also when it is off there is still a dim light for me :(

What kind of led are you using. Link me the product your using. Also, how did you wire up the leds and the resistor.

DIY: Car Modz goo.gl/M2pSA6 I soldered the resistor on the positive wire

You mentioned that you did a mod to fit 3 of those led festoon bulbs... did you install them in series or parallel. Also the resistors need to be install in parallel .. one side to positive.. and the other end to negative.

+KayScotts What car do you have?

2011 grand sport corvett

KayScotts it depends if they all work on one switch then one is probably gonna be enough, now make the calculation..

Tammy Bentley did this work for you? I have the a 2011 GS as well with this problem.

If you have a Euro brand car then you will need to use a error free canbus led and they will turn off completely. I don't think putting it on the fuse will work.

DIY: Car Modz im having the same problem with my Audi. The light stays on i was told not to worry about it but im really anal about things like that. Great Video! What should i do? to resolve this issue

Envy Envy What year and model is your Audi.

2010 audi S5

Envy Envy Is the issue you are having only with the map lights and the glove box? With the light setting switched so that the lights comes on with the doors? And if the switch is turned to "off" the lights completely goes out.

You should be able too. The reason he is having this problem is because this car uses a Canbus system and the Led's are not providing enough resistance to tell the canbus system to turn the lights off. More and more cars are going to the canbus system because is saves on wiring.

+Maharshi Kothamdi Can you link me the drl unit led strips your using. Also what vehicle are you using it on..year make and model and how and where did you connect the red and black wire to? can you upload a simple quick video to show the problem and show me how you have the wires hook up?

+DIY: Car Modz hi, i did not make a video while installing but i can share with you the link from where i purchased a unit and also link to a website that i posted the electric circuit schematics of unit. s.aliexpress.com/bmYzeQba s.aliexpress.com/uYZVBnqM gearheads.in/showthread.php?27636-DRL-LED-indicator-and-turn-signal-circuit-information I hope this helps. Cheers!!

What car do you have and which led bulb did you purchase.

Maciej Skurznica 14.4 Volts / 1000 Ohms = 0.0144 Amps (or 14.4 mA). 14.4 mA * 14.4 Volts = 0.207 Watts, or about a fifth of a Watt... so a quarter Watt resistor should suffice.

+rafidreza It might if you left the car parked for weeks without driving it.

+DIY: Car Modz haha I fitted a resistor anyway. so even if it was dim. it wouldn't deplete the battery over night?

+rafidreza It will be fine.

Even with the LED at full blast, it draws such little power that the battery could probably power it for days, if not weeks.

you can try it won't hurt

What bulbs do you have? link?

Clinton Hemphill It's not that they're not getting enough power, it's that they're getting power when they shouldn't be... it's just not visible with an incandescent bulb because the current going through the filament isn't high enough to heat the wire to the point where it starts to glow, but LEDs are more efficient, and therefore glow more readily.

I would check the switch and also the interior light fuse to makes sure that is not blown. If all your interior lights do not work then the fuse is blown. If only the dome or map light doesn't work then check with the regular bulb to make sure the switch is functional.

Junior Martinez I just put some in my dodge ram 1500 and I found out these LED lights are Polar, meaning one side is positive and the other negative. Switch the lights around in the sockets and they should work fine. 😁 I had the same problem. I was a bit freaked out that my lights remain on but tbh its kind of nice that they do because then at night you have some dim light and dont have to blind yourself with the full brightness of you drop something or if you need to grab something from the seat. So I dont mind them being on really they aren't as bright as the instrument cluster so the little bit of light coming from the LEDs is beneficial enough I will leave them how they are

Zachary I bought new led lights for the dome light and cargo light for my 1500 2003 ram I tried switching them around and it still didn't work they stay dim even when the car is off

they are switched with a transistor. no relay for you!

Dorian Lockett they flicker because they aren't getting the correct wattage and can only dim so far.

+Donny Xiong Yes, I would not let it touch anything plastic or wires.

Thanks, good to know!

Right, it generates heat. I just had mine in for about 30secs and I could see a little "vapor" (cold outside, so you could "see the heat"). What is the safest, largest resistor I can put in to not have my dome light set my cloth roof on fire? What would be the color bands on it?

All resistors will generate heat, that is how they perform their job. If you don't want a ton of heat and have the space for it, install a 1 W rated resistor rated for the same resistance 1000 ohms(the colored bands on a resistor are a way of showing their resistance value). 1 W resistors are much larger, however they will emanate less heat due to the size of the resistor as its built to handle more power. Also the higher your resistance value becomes, the more heat the unit will produce under that same load. so if you can get away with a 100 ohm resistor over a 1000 ohm resistor, them you should be able to produce less heat with the same effect. look up ElectroBoom, he is very good at describing this, and is also very humorous. hope this helped, 8 months to late.

Without the resister

Have you figured out yet?

Actually, it drains your battery. Believe it or not, it had just happened to me. My car had issues starting, I had the whole system checked - battery good, starter fine and alternator charging it. Then I realized that when I have the dome light switch to "door" mode, it never goes truly out, stays lit (very dim, mind you). You'd think that doesn't do much damage, but imagine this over night for 12 straight hours when the temps dip to 0F or even below. My car hasn't started a few times. When I took the bulb out/turned it off, it's been fine since.

Richard Navrátil Not true. After the timeout period (usually 10-30 seconds), the dome light circuit will be faded or switched off. A regular incandescent bulb would be about 2-6 Ohms, so a 1000 Ohm resistor would have far less current drain.

Richard Navrátil also most Vehicles still allow a little bit of current through the lighting system anyway. Kind of like a trickle I guess you could say, with an incandescent bulb it's not enough power to keep them lit, more or less it helps keep the filament somewhat warm so that way if it's winter time and you open your door it doesn't take forever to heat up and light up to its fullest brightness. However with LEDs the current is just enough to keep them dimly-lit. And LEDs have basically no warm-up time

kapitanmike Yes

Online they do

Car computer turns off all the lights after 10 min in some cars, or 15 in others. No problem
