Headlights problems

I have a 2003 Grand Marquis with automatic lights that shut off at random times. Sometimes they are on then they just shut off by themselves. Sometimes they come back on if I hit a bump sometimes they do not.

Possibilities are:

  1. Wiring or connector fault.
  2. Defective LCM (Lighting Control Module).
  3. Defective headlight switch assembly.
  4. Defective light sensor assembly.
  5. Defective circuit breaker.
