for some reason my tail lights aren't lighting up when i hit them to show that i am slowing down, when i turn the lights on my brake light come on but they dont' brighten up to show that i am slowing down, i had this problem once before and it was a sensor that was attached to my rear left tail light. when i replaced it last time it fixed it i replaced it again this time but unfortuantly this time i wasn't so lucky. Anyways so a friend of mine told me it could be the brake switch underneath behind the brake pedal so i replaced that too!! And i hope none of you guys ever have to replace that because it's hell trying to do. anyways i replaced the switch and the problem is still there, Oh and i also checked the Stop lamp fuse and it was good to so i have no idea what it might be

I'm starting to think maybe it's my wiring to the sensor on my rear left tail light maybe it's gone bad.

if anyone could throw me some info i'd appriciate it peace!

maybe you already did but did you check the bulbs? sometimes its the easy stuff that gets you. brake bulbs have 2 prongs and these go bad often.

I would start by checking the fuses. Then take a test light and test the brake switch at the brake pedal. You should have power on one side, when you depress the pedal you should have power on both sides. If you have power on both sides then brake switch is working. Pull tail lamp sockets out and check for power and ground.

I figured it wouldn't be the actual bulbs because they were working before when i replaced the senor in the back the first time, and i figured what would be the chances that all bulbs would go bad at the same time!! I guess i could checkt to see if i am having power on both ends, but my brake switch now is brand new so it should be working but i'll check just to be sure!! Thanks you guys!

Just because the switch is new doesn't mean it has power going to it. I would check things with a test light before replacing unnesessary parts. Remove the tail light bulbs and test the sockets to see if you have power on them. Also check to make sure you have a good ground. They won't work if either one is missing. Using a test light will tell you where you have a good circuit and where you don't.
