Have you checked your brake fluid level? Sometimes, when the brake fluid is just a <little> too low, the brake error light will come on momentarily.
Sometimes parking brakes also stick a little (the cables tend to bind occasionally). This could also be your problem (although I rather doubt it).
Failing this, a quick check of the rotors, calipers, pads, fluid levels and system operation would be advisable.
Hope this helps, Sherwin

The brake switch under the dash has either loosened or is out of adjustment or needs to be replaced. You will see a plunger on the switch when you depress the brake pedal. It is about half way up the brake pedal lever. If it is stuck in, sometimes a little silcone spray will free it up allowing the brake lights to come on. It can also be adjusted I believe. This is usually where the problem is. The only other thing is a broken power wire. Good luck!

I've had this problem before. What I found was a bulb socket which was wired for two filaments and a single filament bulb was plugged in the socket. A single element bulb will set between the two filament socket and effectively short the two.

first thing is to get the OBD codes checked, But in the past Ive had similar questions asked like yours, the majority of the problems stemmed from a bad battery, not necessarily dead, But one with a bad cell , have your battery LOAD tested, if you have a walmart near you they do this for free, with a machine, Not just a hand held check, it checks each cell with very good results. If possible have the alternator checked too,
