Ok for some reason I can only post here so here goes. I've owned my car for 3 years now and aside from a faulty coil and fuel pump it's been good to me. My issue now is I installed a lebren light in the bumper. I opted to wire it as a running light and as a brake light. After a few months if I turned my lights on it would light up fully bright as if I was riding the brakes (my normal tail lights were acting normal) and then my Abs and Tcs lights would come on and neither would work. Keep in mind this was only if I turned my headlights on. So seeking to diagnose the problem I cut the wires for the lebren light to make sure it was the culprit. In the last 10 times I've started it the abs and tcs lights immediately came on when the car was started and the 10th they came on when lights were turned on. Is there something I am missing?

Very difficult to know what the issue is. It is very possible that they are unrelated.

you should gave codes in the ECU for potential errors. That would be a good place to start.

to my knowledge it doesn't have any codes. I can try scanning it again later if need be, but last time I did there was nothing.

It seems like you have two separate issues, but they might have a common source.

The first being that you likely have a short somewhere in your wiring, which is causing your aftermarket light to act as if the brakes are always depressed.

The second is that the ABS/TSC is turning off. This is a common problem when replacing the rear brake lights with LEDs because of their lower resistance. I'm not sure why it affects the DSC/TCS system, but if you have a short it could definitely be causing the system to fail in a very similar manner.

I spliced the lebren light into my left taillight. That taillight still acts normal so it shouldn't be a short in the wiring unless it is in the brand new lebren wiring. And none of this explains why now that I've cut out the lebren light why my abs/tcs or inactive independent of the brake lights.

You said you cut the wires going to the light, but did you inspect the area where you spliced off from the tail light?

I used the kits included scotch connectors so I doubt it has anything to do with that splice. Though next chance I get, probably monday) I may just cut those out and re solder the wires for the left tail light both without the light and with to see what happens.

I installed on of those Lebren lights as a brake only from the drivers side wire several years ago and no troubles.

I also installed a flasher which changes the electrics somewhat.

Flasher pulses very fast and then brake light stays full on.

Ended up being the power wire going to the third brake light. It was grounding itself out, causing the problems. Got it all fixed.
