    I have LED turn signals. One light is not working, seems to be bulb but, could it be another issue?

    I would first check to see if theres power at the bulb socket. Process of elimination, start at the source.,

    A test light or volt meter will be a good start

    LED's are polarity sensitive.
    Regular bulbs will work, no matter the polarity from the factory.

    When I replaced my lights w/LED's, one side didn't work.
    Even when swapping.
    Then I checked the polarity at the socket.
    It was reversed from the factory.

    Took a little time and got the leads swapped around and then it worked.

    Check the polarity!
