Check your light bulbs, the two filament bulbs can shorten out on a filament when the brake is applied. Make sure you have the right bulbs in and check the wiring harness on your lights and take a look inside the light assembly for any short circuit. Also any addition like the third brake light and, like mayer said, a trailer light plug that is shortened can do it too. Good Luck to you
