have you done any work on the taillight? it sounds like you have a problem with the brake lights. usually, if the light blinks fast, that means there is a blown light somewhere. if there wasn't any work done on the taillight, check the relay under the dash. i believe it is a blue box about 2" x 3" x 1".
