The brake light comes on randomly.

Brake lights that come on intermittently are likely caused by a faulty or misadjusted brake switch. The problem could also be caused by a short in the brake light wiring. A trained technician, like one from YourMechanic, will be able to diagnosis and repair your brake lights saving you the hassle.
