I've tried using working bulbs, doesnt help. I think it may be the tail light failure sensor relay but all the other tail lights work including inners. This all happened after trying to install the LED tail lights by Jun Yan. Absolute junk dont ever buy them.

Check the harness and connections. Only thing I can say.

I say do not bother with aftermarket LED tail lights. I had some on my last GS and it completely burn all of my brakes sensor relay and throwing off all sort of lights on my dash. The repair job was over $1500 if i remember correctly but luckily it was still under warranty.

Anyways to help with the problem try trouble shooting: check your fuse, check all light bulbs if any are burn replace them with working one. Just in case its wired together. This includes 3rd brake light in the back window (three 194 bulbs i believe), license plate and trunk. Inspect the bulb harness socket for bad pins resulting in failure to contact with the bulbs. And a simple double checking if all is connected tightly. Good luck.

Almost positive it is the wiring harness. I hooked up the left light to the right side and it worked fine. Can't be the bulbs either. The only other thing it could possibly be is the trunk failure sensor relay thing. But that usually shorts both sides. I shouldn't have even bothered trying to hook these tails up. I had the same brand mailed to me once back when I had my GS430 and the same thing happened. I don't know why people bother selling this junk. The tail lights not only shorted my harness but they also didn't even come close to fitting on the car due to the capacitors being placed on the side of the tail lamp.
