Start and Stop
The OEM headlight switch is overloading and the integral circuit breaker is tripping. Unbelievable. Ford had this issue 38 years ago and never fixed it.
Either patch it up with a new headlight switch replacement
Or add a relay to power the small BROWN wire the exits the cab and powers tail and clearance lamps.

Tail lights relay installation.
Really, Ford had a supposed issue 38 years ago and you state it must still be an issue????? There are tens of millions of these Ford switches out there. IF there was a supposed defect, don't you think there would be a great outcry on this supposed problem? The simple fact is, the OP has a 18 year old Headlight switch that has failed from 18 years of current flow. Just replace it, NO BIG DEAL. Doug
