Tail Light Issues

[RBceffy25]

I own a 1990 nissan Cefiro.

One side (RH side) of my tail lights will not work but the brake lights are fine.

I have checked the fuses, the bulbs and replaced the relay but they still wont work!.

I put a test light in the bulb socket and there not getting power but the brake light still work fine when the pedal is pressed.

What the hell is going on with it?

A wiring diagram for a A31 cefiro would be helpful to if anyone has one?

They use a twin filament globe - 1 filament for the brakes, 1 filament for tail lights. That is why the brake light works, but the tail light doesn't.

If there is no power to the tail light terminal, then either you have blown the fuse for the RH tail lamp, or the power wire to the RH tail lamp is broken somewhere (have fun finding that one!)

why dont you just run a lead from the tail light on the otherside.. ie left is playing up.. run a lead from the right one?
