LED Tail Light question

JetBlackE46 · 06-11-2008, 04:35 PM

I believe that aftermarket kits use resistor boxes to avoid the bulb failure light by "fooling" the LCM module. I'm concerned about the resistor boxes getting too hot and potentially starting a fire or melting something.

Anyways, I was wondering if I bought aftermarket LED tails and did the dealer reflash, could I NOT use the resistor boxes???

yes

Depends on the year of your car.

I'm also gunna guess that you will still need some regardless since LEDs in general require completely different amounts of power to your stock setup. That's something reflashing won't solve.

Any update on this? I have the same concerns and would like to upgrade to LED tails without using resistors/load equalizers.

I have never tried this but the resistors are entirely insulated and do not heat up so you don't need to worry about running them in the trunk.

i need resistors for my car because i have leds instaled for the rear lights but they blink and on the inside it comes up on the panel. anyone know what resistors i need?

Do you have OEM or aftermarket tails? If they are OEM, you will need to go through an LCM retrofit to get them to work properly.

Not necessarily. Depends on the build date of the car. My car did not require a new LCM.
