car is completely stock, never been modified.. brakes and all other lights worked fine.. just few days ago i made sure brake lights are good.. today one of my friends was driving behind me to tell me none of my brake light work... managed to get pulled over on the way home to fix it by the dear CA popo's! hhahaah.. and all that chat we had on getting pulled over ref'ed and etc.. i was balls were shakin' haha.. luckily good old sweet talk got me out without them asking a single question besides tailights..

anyways back to problem.. checked all fuses, bulbs and etc.. i'm thinking its the brakeswitch by the pedal.. they both look in great condition.. no loose wires and etc.. question; does the switch need to click when brake is pressed in? if someone could just advise on how that system operates if possible.. many tks!

the switch does click but I dont think you will be able to hear it...you can check the circuit by pulling the harness off that switch. you can use a test light and one wire should always read +12V the other wire will read nothing. you can trying jumping those two wires with a paper clip or wire and have someone check if your brake lights turn on. if they turn on then its probably your switch or some bad wiring. to be extra sure you can run a continuity test with an ohmmeter on the switch...

when the brakes arent pressed, the switch on the brake sensor stays in. A rubber grommet on the brakes holds the switch down, keeping your brake lights from coming on. When you press the brakes, teh grommet no longer holds the switch down, opening the circuit, allowing your taillights to be on.
