Had that happen to mine and it turned out to be the trailer brake unit being faulty.
Obviously it was the stop lights on mine but worth a look if yo have a unit.
Cheers

 

I have the same issue right now. My tail lights and number plate lights don't work. Stop lights are working fine. I have found that the wire comming to lamp sockets is corroded and lamp sockets also corroded. I changed about 2m of this wire and changed lamp socket aswell. Also sprayed lamp sockets with anti corrosion oil.

 

check yer grounds!

 

If it is brake lights there is a rubber stopper on the brake pedal that turns off the brake light switch, i had mine fall out and there for the brake lights wouldn't go out.Just glued the rubber stopper back on and all good again.

 

Thanks everyone for suggestions.

Thanks Vanderbro I found my rubber stopper broken in pieces on the floor mat in the mud, need new one.

 

We had massive dramas with one trucks lights working on and off too. Turned out to be connection under the passengers seat. It's under the black cover and it connects the front wiring loom to the rear one.

Fix was some contact cleaner and a good old push back together and we had all lights going again.

Let us know how you go.

 

Same problem with mine on occations,i thought it may have had something to do with the brake controller as well.What brand controller is it?

 

its not a stoper its a in out switch. about 3/4's the way up the peddel arm

 

Cheers, my lights turn off when I push the switch in but the rubber stopper has gone, I have pulled the fuse out to stop lights for the time being.

 

i just put a bolt in there. grind bolt till its the right thickness and bobs your uncle. cost me all of 20 miuntes haha. saves giving nissan dollars they dont need.

 

Thank Benos, great idea.

 

happened to my old 89 as well and the in laws GU. Must be damn common, i just put a bolt in....fixed forever and more in the good books of the inlaws although he already had the wiring out everywhere which i reluctently had to shove all back in...lol wish i had of got there earlier.
