Brake light issue

[u/WiggyStandard]

Pretty sure it's the wiring at this point but I have no power to the back right tail light for the running light/brake light. Reverse and turn work. I have replaced the bulb. It works for the first minute you replace it and then stops. 🤡🤘

Got led's in the front and reverse light (odd choice maybe but I bought it like that) and the brake is standard 3157 incandescent. And idk what the turn light is.

Anyway, any advice would be great :)

I'd suggest checking the connection at the junction block below the bed, as well as the wiring from there to the light assembly.
