Re: '48 Head Light Switch & Circuit Breaker

The switch assy removes from the rear. Chrome stays in place. One special nut is located next to the headlight switch and is sort of hidden between it and the next switch over. The other end nut is between a couple of smaller or less congested switches and more easily seen. You will most likely have to drop the vent control assy for access and to allow the assy to drop down.
The breakers have been known to lose capacity with age but also don't forget the breaker also protects the parking, dash, tail, license, and trunk lights. A short to the body at one of the grommet penetrations in the trunk or fenders is a possibility as is the insulation shrinking back or cracking off where the wire enters the shell at one of the lamp sockets. The loom in the trunk is a known area that has been damaged by things sliding or hitting it. The license light wire goes thru the trunk floor and that grommet is frequently hard, damaged or missing.
Any damage anywhere could allow a short and the breaker will cycle until vibration might move the wire or the breaker fails.
I'll take the liberty of borrowing a couple of photos posted by BDeB showing the nut locations.
