When your brake lights fail, other drivers might honk at you and police might pull you over, as brake lights are crucial to safety. What causes them to fail?
If your vehicle’s brake light keeps going out, you’re probably beyond frustrated. Whether it’s the second time or the fifth, this issue puts your safety at risk and interrupts your week. Let’s dive into four common reasons behind this issue and how you can fix them.
1. Faulty Bulbs
The most straightforward cause of a brake light going out is a faulty bulb. Bulbs, like all things, have a limited lifespan. Over time, they burn out and need replacing. Always check the bulb first when your brake light stops working. If the filament inside the bulb looks damaged, it’s time for a new one. Keep spare bulbs in your car for quick replacements, but be cautious if your car gets hot—excessive heat can ruin bulbs, leading your replacements to fail.
2. Blown Fuse
A blown fuse is another common issue. Fuses protect your vehicle’s electrical system by preventing overloads. If the brake light fuse blows, the brake light will stop working. Locate the fuse box in your vehicle and identify the brake light fuse. If it’s blown, replace it with a fuse of the same rating. Always carry extra fuses in your glove compartment.
3. Wiring Problems
Wiring problems can also cause your brake light to malfunction. Over time, wires can become frayed, corroded, or disconnected. Inspect the wiring leading to your brake lights for any signs of damage. There are several different kinds of connectors in our vehicles, but pin connectors are the most common. If these connectors come loose, they can cause your brake lights to malfunction. Reconnect any loose wires and replace any damaged ones to resolve the issue.
4. Brake Light Switch
The brake light switch is located near the brake pedal. When you press the pedal, the switch activates the brake lights. If this switch is faulty, the brake lights won’t turn on. Press the brake pedal to check the switch and see if the brake lights illuminate. If not, the switch may need adjustment or replacement. This is a more complex fix and may require professional assistance.
Your vehicle’s brake light may keep going out for several reasons, including faulty bulbs, blown fuses, wiring problems, or a malfunctioning brake light switch. By understanding these common issues, you can troubleshoot and fix your brake light problems, keeping you safer on the road. Always promptly address brake light issues to avoid accidents and ensure your vehicle is roadworthy.
