I had the wire come off my pressure switch and didn't know until someone told me my brake lights weren't working. Because I'm anal, I mounted a mechanical switch to my under floor pedal wired in parallel with the pressure switch (either or both switches activate the brake lights). This switch adapts well;

Then because I'm incredibly anal and didn't like the idea of not knowing when my brake lights were not working, I took my third brake light mounted in the rear window apart an wired an LED into it. Biased the LED dim and faced it so I could see it in the rear view mirror. Now I know when my brake lights are working. I told you I was anal, LOL!

Next a very loud peizio buzzer wired to a micro switch on my parking brake handle. Lol..
