Although it's possible there could be other reasons, the most common causes for brake lights to stay on continuously include:
- The brake light [if mounting position is adjustable] is out of adjustment, or
- The brake light switch contacts are fused ["welded"/melted] together, or
- The brake light switch is otherwise defective.

Why might the brake lights on a 1990 Toyota Camry not work?
well if you have allready cheaked the brake fuse it could be that the bulbs have burnt out check that.......As for me we tried to go the easy way with installing a toggle switch and manually turning them off and on, but today the wires melted completely from the battery to the brake lights themself, as of tomorrow we are going to buy a brake light switch and install it. I was told that is what is causing all of this trouble. I hope I helped.
