My headlights will start to go on an off when I have the headlights on .Takes a shorter period of time to start doing this when the high beams are on rather than the low beams. My regular driving lamps won't do this ever. help much appreciated

 

That could be bad wiring, or bad switch.

Check all your connections. It sounds like a loose or abraided wire.

 

Thanks, it was the headlight switch.
