    Having a weird situation with the trailer.

    The driver side amber turn signal doesn't turn on with every other light, but it works/blinks once the turn signal is activated.
    The passenger side turns on, stays on, and blinks when signal is activated.

    Have you experienced this before?
    Currently confused on which one working correctly!

    The passenger side is working correctly. Remove the light from the pass side and replace the driver side. If it works go buy another light.

    And if it doesn't work, check the plugs, terminals, & power wire.

    There should be a ground, power, and a blinker wire.

    Well now that it’s dark and I made a left turn, I noticed that when I apply the brakes, the light turns on. So I’m thinking the bulb is good and it’s an electrical issue.
    I tried the rear port on the truck, still nothing so definitely the trailer
    I’ll try to figure it out over the weekend.

    Alot of small trailers are just wired that way. The manufacturer just ties that side turn signal into the same circuit as the brake, turn, tail light. My LoadMax was the same way. Hit the brakes, & the side blinkers light up solid amber in sync with the brake lights.. LoL

    If they are not led, the dim filament (marker) is probably just burned out. If they are led, you may just have a defective light, wiring, or bad connection..

    Do what @Slay said & swap lights with known working one to see if it's just the light fixture itself..

    Yeah I have the Load trail. It was the light. Switched it out, now they both are always on.
    I don’t like it because it makes the blinking not very noticeable when looking at it.
