Thanks for the help with my last question. A good ground got both filaments working. Now I have a new problem. When the brake is depressed and the turn signal on, the blinking filament is barely visable and makes no difference in the brightness of the lens. When the headlights are on, the new lamp is brighter than the old one and depressing the brake brightens the old light and then they are the same brightness. My question: did I get the wires crossed when I rewired them? The truck has a green wire and a black wire, and the light has a black wire and a white wire. I went black to black and white to green. Should I disconnect them adn reverse the wires to get it to work right? Thanks in advance for your help.
