My old tail lamps were old, cracked, and not very bright. Sooooooo, I decided to find something more efficient, brighter, and not cracked. From a member on the corvetteforum.com, I was directed to led tail lamps from a tractor trailer. Yes, I said a tractor trailer. They are the perfect size, and since there were no led tail lamps being made for a c3 corvette, I figured i'd try them out - at 10 bucks per light, I figured I had nothing to lose.
