i have a 92 cb7 and the passenger brake light and 3rd brake light (top break light) arent working.
parking lights work fine but when i brake the dont come on.
iv bought a new light for it already and replaced it, it worked fine for a bit then stoped working again.
not sure if thers a open wire burning the bulb quick, or just something wrong with the fuses or something.
if anyone could let me know what you think it is please any help would be appreciated.

 

It may be an issue with the right light failure sensor; located in the rear. The high mount and the passenger side brake lights' power source runs through it.
