Trailer wiring issue. brake light and turn signal don't work with head light on
The brake light and turn signals work when the headlights are off, but when I turn the headlights on, the turn signals and brake light no longer do anything, it just stays lit. Trailer lights are 2 wire, dual filament, and ground to frame.
