In the summer, I installed a Buggies Unlimited Universal Economy Headlight Kit on my Club Car DS. This week, I installed an Economy Universal Black Taillight Kit from you on my Club Car DS. This taillight kit had no instructions included, but should have been a simple connection because it had the same black and white wires as the headlights and the additional red wires for the braketurn lights. Wrong!!! - after connecting all the wires in the logical combination, the brake lights would not work if the lights were turned on. After further investigation and taking apart a taillight assembly, the problem was found. The black wire is used as the common wire on the headlight kit, but the white wire is used as the common wire on the taillight kit.
