Rear taillight Resistor
Hello everyone,
Doing custom taillights for the GS. Wanted to know what resistor should I use, since he typical ones will overheat pretty fast on me.
Any feedback would be appreciated.
Thanks.

I went with the ghetto fab fix pulled the cluster out to remove dash light bulb. Just keep an eye on them to make sure there isn't a rear bulb out because if there was dash won't indicate it. There's other threads about ways of going about it but that just seemed most to the point to me. Didn't want to mess with/risk accessing the little box in the trunk, snipping wires, etc. Happy trails! Please share the results once you have them together!

So originally I was going to do something custom but I lucked out and found a set of LED taillights online.
The guy who i bought them from stated the taillights would through a bulb out error. So thinking it is because of the set not having a resistor possibly.
He stated none of the LEDS are out so a resistor may be the fix.
Any thoughts?

If I remember correctly, our tail sensor runs off a 3 wire circuit, something like one power, one ground, one for the sensor. Not sure how the resistor would be installed; I never studied the circuit schematics for that, I need to though
BTW, having one LED out (or any number) wouldnt make the sensor go off. LED's run off such a low voltage that the sensor doesnt detect the 12v being drawn as by a normal filament bulb thus the system thinking its burnt. The catch 22 with load resistors though is that they only stop the dash lights from going on, but you'll never know if you do have a tail light out. Same when using LED blinkers. You can get an LED relay or use load resistors on them too, but that only stops it from hyper blinking (which is used to tell a driver that the bulb is out).
