This popular kit will provide turn signal and parking light functions to your original 682-C's. You get 2 each, new sockets, gaskets, and high quality 2 filament "Clear" lamps. The common 1157 lamps will not work because of the large 1" diameter of the glass envelope. Our lamps are .72" for plenty of clearance. Your only modification is to slightly enlarge the socket hole in your headlights to 3/4". We include directions of course.
