Which switch for my '53?
Mid Fifties catalog shows two different brake light switches(hydraulic) one is supposed to operate at 20-50 psi( the higher priced one).The other must operate at a higher pressure, I'm not sure that is what I want/need with a power booster, though. Isn't the pressure higher in a system with power brakes? Not a big issue here but I'm just curious

I'm not fond of a hydraulic brake light switch, they have a nasty habit of failing and/or leaking. Why not just put a mechanical switch on it for reliability?
To answer your pressure question: No, power and manual brakes use the same line pressure to stop, the booster just makes it less effort on the right leg to reach that pressure. The lower pressure switch turns the brake light on sooner giving the guy behind you a little more warning.

I went with the adjustable brake light switch mid fifty sells. Mounts between the floor and pedal arm. this switch is mechanical and seemed to be the most trouble free and reliable. They are $20 part# 0576
