Brake lights
I have gone thru 3 of the pressure switch on the master cylinder. Does anyone have a better alternative than the oe style?

Are you using something other than DOT3? Have you try a different supplier? I've use the NAPA SL134 and DOT3 without issue.

.... or, you could run it into a relay so that then the switch would only have to carry just enough current to trip the relay and the relay would switch the rest of the load.

Are you by chance using silicone brake fluid?It loves eating up those pressure switches because most of them are not compatible.

Mine did the same thing. A lot of them do that. I went and got this switch from Summit. Item #rfw-sw68. Don't know why I can't make a link work.
