Trailer lights?

[BALLS DEEP]

Why is it that when I hit my brakes the tail lights go out and I have no light to the tail lights? Once I let off the brakes the tail lights come on again. Thanks in advance,

Sounds like a bad ground.

Add a wire to each tail light where they attach to the frame and run it to the white connector wire of your connector. Trailer frames are corroded after time and a  copper wire to your system saves a lot of headaches . Run the wire from one light to the next and then to your connector.
