I'm getting the finishing touches on my project and I've run into a problem I can't figure out. the wiring is all original and looks nice.
On my left rear I have fully functioning stop, turn and marker lights in the rear.
On my Right side I have marker lights, and turn and stop but the lights are dim, and the blinker stops when I turn the marker lights on. only one element of the two elements on an 1157 bulb are working. I reversed two wires and it only made it worse, then the bulbs dimly glowed on the left side. I put it back to the way it was and changed both bulbs, still both are burning only one element.
