What Is Making My Brake Lights on My Car Go Out

Car Brake Lights | Fuller Automotive in Auburn, MA

Driving without brake lights is not just a bad idea - it's a safety hazard! Brake lights are your vehicle's way of communicating with other drivers on the road. They signal your intentions and help prevent accidents. So, what happens when these crucial lights decide to go MIA?

1. Burned-Out Bulbs: One of the most common reasons for brake light failure is simply a burned-out bulb. These bulbs have a limited lifespan, and when they reach the end of their journey, they go dark.

Solution: Replacing the bulb is relatively straightforward. Refer to your vehicle's manual to locate and access the brake light bulb. Ensure you choose the correct replacement bulb, and follow the manufacturer's instructions to install it.

2. Faulty Brake Light Switch: The brake light switch, located near the brake pedal, is responsible for activating the brake lights when you press the brake pedal.

Solution: If your brake lights aren't working, a malfunctioning brake light switch could be the culprit. A professional auto technician can diagnose and replace the switch if necessary.

3. Wiring Woes: Over time, the wiring that connects your brake lights can become damaged or corroded, disrupting the flow of electricity to the lights.

Solution: Inspect the wiring for any visible damage. If you're not comfortable doing this yourself, a qualified mechanic can identify and repair any wiring issues.

4. Fuse Fiasco: Your vehicle's electrical system relies on fuses to protect it from power surges. If a fuse blows, it can cause your brake lights to malfunction.

Solution: Check your owner's manual to locate the brake light fuse. If it's blown, replace it with a new one of the same rating. If the new fuse blows again, it's a sign of an underlying electrical problem that requires professional attention.

5. Dimmer Switch Dilemma: In some cases, a malfunctioning dimmer switch can affect the brightness of your brake lights.

Solution: Consult your vehicle's manual to locate the dimmer switch and test it for issues. If it's faulty, replace it as needed.

6. Brake Pedal Sensor Snags: Modern vehicles often have sensors on the brake pedal that can fail, leading to brake light issues.

Solution: If a faulty sensor is identified, it's best to have it replaced by a professional.

Remember, functioning brake lights are not just a legal requirement in many places, they're a crucial safety feature. Regularly inspect your brake lights to ensure they're in working order, and don't hesitate to seek professional help from Fuller Automotive in Auburn if you encounter any issues. Safe driving starts with visible signals!
