Another possible cause is a faulty brake light switch. This switch activates the brake lights when you press the brake pedal. A malfunctioning switch can cause the warning light to illuminate erratically.
Sometimes, a worn or damaged ABS sensor can be the culprit. The Anti-lock Braking System (ABS) prevents your wheels from locking up during hard braking. A faulty sensor can disrupt the system, triggering the warning light.
