Okay guys, I still have the warning light problem...

The red light that looks like a headlight illuminates when you press on the brakes. Per other members' suggestions, I've checked/replaced all rear lights, including the three in the turbo spoiler. I've also filled up the brake fluid resevoir. THE LIGHT STILL COMES ON!!! Arrrggghhh! This is frustrating. Any help out there? Is there a plug for that sensor that maybe isn't plugged in or a fuse or something? Thanks!!!!
