ok well the other day i noticed my left tail light had gone out, well i stopped at a gas station that had tail lights and bought some, i tried to take the old tail light out and it broke and turned on and shocked me, at which point i relized i was stupid and forgot to disconect the battery, and then i did, well i put the tail light in and YES it was the right one,(with two filaments) and then i got in my car and put it in reverse and it didnt look like they were lighting up, (yes i put the battery back on) so i got out and asked the guy at the gas station to push the brake, they were on, but werent lighting up when you push on the brake, i was pissed but whatever, i got in the car and checked all the fuses and they were ALL fine, even the ones under the hood, then when i started the car and started driving, and pushed on the brake to stop my light came on for my seatbeat and door being open, i opened the door and closed it and checked my seatbeat, everything was fine, now i have relized every time i push the brake it shows these lights and makes that horrible sound, BEEP BEEP BEEP BEEP, of when you take your seat beat off when driving, anyone ever heard of this, how do i fix it, pleaseeeee help??????? im going crazy, and my brake lights still dont work.
