feel free to move this to electrical if need be,

my 82 has 86/SVO/Cobra style tail lights the rear valance was modded (cut) to fit the turn signal bulbs, now when my lights are on both bulbs are lit up on the same side and when i put the 4 ways or turn signal on both bulbs flash on the same side, except the pass side it just stays lit no flashy.

where should i be looking for the problem could the TSS be bad maybe? i havent tried to see what lights up with the brakes on my guess is both bulbs.

did they work like normal brake and turnsignals where only one bulb would flash the other would stay solid while turning and on the brakes?

gonna need a wiring dia and see if anythings been hacked. What are the number on the bulbs? That will tell us the function of them.

they are both 1157's dual filament, the wiring looks untouched, but being as the 82 lights were all red is it possible that both bulbs would flash and be on with the marker lights?

like in this video all 4 bulbs in the rear are lit up with his markers on...
