    I have a 14 freightliner cascadia..and my tail lights work somewhat..signals, hazards, brakes..except my reverse light isn't working..and the problem with the 2 others lights is that they are on..but they are super super dim..to the point you cant even hardly see em at night!! Anyone have any ideas??

    Dim lights are often caused by a bad ground.

    Try to ground your lights directly to the frame.

    With lights, a bad ground can make your lights go crazy and do things you could never imagine.

    Sounds like either a power supply problem or a ground issue. Since the grounds typically go to the frame, they tend to rot after a while.
