i just bought i new bulb for me 1985 350x rear "brake" light and it doesn't work, i jiggeled the wires aliitle but nothing. It did work in the past, but i saw that the bulb was blown so i got a new one, but nothing when i put it in. The front lights work fine. Anybody have any tips for me?

 

are you getting power though the rear light wires?
if you are mess around with you light, it might have a bad ground.
or cut the old ones off and put new bigger gaged wire on it.

 

do your headlights work? if they are not working your rectifiyer may be bad. That is the 2" by 3" finned box held on by 1 10 mill. bold right behind your seat latch
