Replace your brake light switch

This happened to me a few months back, seems like it's pretty common on our cars. Replace the brake light switch located directly above the brake pedal arm (use lots of lighting and prepare to work in a tight space, on your back).

Here's a pretty good link covering the procedure involved:
