A multimeter is a good tool to check for a short in the brake light. Put one end of the meter on one side of the wire near the brake light. Put the other end on the metal that is around the bottom of the bulb. If the bulb does not light up, there is a short. If the bulb lights up, there is no short in the wire.

Check for a short in the brake light circuit. A dead short will dim lights & blow fuses. Have you checked the charging system & battery? Pull the fuse for the brake lamp circuit & see if the same problem still exists.

It's because you have a short current somewhere. You need to check the brake light wiring.

check your brake fluid level under the hood. This may be true if the brake light is in the dash . If the light your talking about is the actual brake lights on the rear of the car you probablly have a short in the steering column
