I've checked everything.. Whenver i turn my lights on in my 92 cam. all my lights turn on except my tail light. although when i go to brake my tails light up.. all of them. So when your riding behind me at night all you see is the small side rear markers that are red and nothing else untill i brake. I've switched tha bulbs tons of times. its not that i'm puttin in the bulbs that only have one light filament. i got tha correct bulbs that are supposed to be on and then get brighter then i brake. i just dont know whats goin on. i checked fuses what else is there to check...
