I have a truck above all lights work except for abmer running side on left only. Its a amber 1157 . Yes bulb has ben changed

International prostar

I had this issue it was wiring inside the connector down from the headlight I think it was a brown wire on my truck. Follow the wiring back from the light to the connector that's probably about a foot and a half to 2 feet away from it on the frame rail and then pull the connector apart and look at the pins and also see if the wires are actually secure in the connector.

Thank you that gives me a place to start

Mine was corroded in the connector.So bad the male pin was gone. I just cut the wire on each side and bypassed the connector with a wire. been that way for 2 years now.
