Why Your Brake Light Stays On: Common Causes: 1 Minute to Understand Why Your Brake Light Isn’t Turning Off

If you notice your brake light stays on after releasing the pedal, it’s crucial to address the issue promptly for your safety. There are several common reasons why this happens. The most frequent cause is a faulty or misaligned brake light switch located near the brake pedal. This switch is responsible for activating your brake lights when you press the pedal, and if it sticks or breaks, the light may remain on continuously. Another reason could be low or leaking brake fluid, triggering the warning light on your dashboard. Sometimes, stuck brake calipers or a malfunction in the master cylinder can also lead to persistent brake warning lights. Damaged wiring or blown fuses are less common but can still impact the brake light circuit. To solve the issue, inspect the brake light switch, brake fluid levels, and check for any visible wiring faults.
