I have a 2003 LS430 and I switched to LED after market tail lights and the tops of all the lights don't light up. All 4 pieces are the same. Anyone have any ideas? Is there a seperate fuse somewhere for the top half of the lights? I don't get any error messages on my dash but still they don't work... So any direction on this would be greatly appreciated

I would first swap in the old style to see if they all work, but aftermarket led's are usually cheaply made and don't last nearly as long as people would have you believe.

My guess is it's simply defective LEDs and not the car itself at fault.

Double check your wiring. The black wire from the new harness needs to plug into the white wire with a black stripe from the harness you transferred over. I had the same issue, after actually starting the car all of my LED lights work perfectly now.
