mine has been goin off sayin that all tha time since i bought it 2 years ago, its supposed to mean that the circuit has blown out, but ive noticed it only happens to me when I start the car with the breaks depressed or I hit the breaks hard.
... use only Oem bulbs some cheap replacements dont have the proper resistance...

Hi, here is a link to help you with your brake light circuit failure.......most of the time it is the brake switch when everything else checks out ok, but sometimes you could have an aftermarket bulb that does not make good contact in the light socket, but lights & that slight loss in continuity is enough to give you that B L C F warning. So make sure you have clean & solid contact between the bulbs & sockets....
