I'm trying to convert my old 38 Chevy tail lights to LED. The lights I ordered are direct replacement tail lights. I can't get them to work. I have power to the light and when I hook my old light up it works. Now the LED's have a red wire, a black wire and a white wire. I am assuming the black is ground and red brake & turn white park. They didn't arrive with directions on how to hook them up. No matter how I hook them up they will not work. I can't see both new lights being bad? Any one worked with this type light? Someone told me I had to change flasher to a electronic one. I did that and still nothing. Thanks for you help!
