    All my lights work just fine, even my running taillight on passenger side works, but my driver side running taillight doesn’t work and it’s not the bulb, any idea on what it could be or how I could fix this?

    Do the license plate lights work?

    Green wire is power.
    White/Black is Ground.

    We need to see what is missing.

    Are the tail lights OEM?
    And are they LED?

    They were OEM and the light was out and then I switched them to aftermarket LED thinking it was a bulb issue and it’s still out.

    Do you have a meter? Have you probed the socket for power? Is the socket shiny clean?

    Well my brake lights work on that taillight and it’s the same socket so I don’t believe it’s the socket, is it possible for it to still be the socket?

    Probably not. Curious if the LED is not getting sufficient voltage to fire.

    You might want to try swapping bulbs side to side to rule out a defect with the bulb.

    You tried flipping the LED around? Filament bulbs don't care about polarity. LEDs being diodes typically work in only one orientation.

    The stock bulb is a 3157 dual filament bulb with two sets of contacts. Is the LED designed to replace a 3157 bulb with two brightness levels (running light and brake light)?
