What does it mean when your brake light is blinking?

When your brake light blinks, it typically indicates a drop in brake fluid levels, often a sign of a leak. It is important to refill or add brake fluid to resolve this issue. However, if the blinking persists, it is crucial to have your braking system inspected by a mechanic for potential leaks.

Additionally, a flashing brake light can also be caused by overly sensitive brakes or low battery voltage, which may require professional assistance or battery replacement.

Common causes of flashing brake light

1. Engaged parking brake

One common cause of flashing brake lights is an engaged parking brake. If you accidentally leave your parking brake engaged while driving, it can trigger the brake light to flash. This serves as a reminder to release the parking brake before continuing your journey. Always double-check that your parking brake is fully disengaged to avoid this issue.

Flashing brake lights can also be caused by damaged brake light bulbs. Over time, the bulbs can become worn out or broken, resulting in intermittent flashing. Regularly inspect your brake light bulbs for any signs of damage or dimness. If you notice any issues, replace the bulbs promptly to maintain proper visibility and ensure other drivers can see your braking signals.

4. Overly sensitive brakes

Some vehicles may have overly sensitive brake systems, which can cause the brake lights to flash even with slight pressure on the brake pedal. This sensitivity can be due to various factors, such as a misadjusted brake switch or a malfunctioning brake pedal position sensor. If you experience this issue, it is advisable to have your brake system inspected by a professional to determine the cause and make any necessary adjustments or repairs.

5. Low battery voltage

Low battery voltage can also contribute to flashing brake lights. If your vehicle’s battery is not supplying the correct voltage to the electrical system, it can cause various errors, including the flashing of brake lights. Additionally, other electrical components may exhibit issues, such as flickering lights when the car is idle. If you suspect a low battery voltage, consider having your battery checked and replaced if necessary to rectify the flashing brake light issue.

6. Low brake fluid

The most common cause of flashing brake lights is a low brake fluid level. This indicates a potential brake fluid leak in the braking system. It is crucial to check the brake system for any signs of leakage when the brake lights start flashing. If you notice any fluid leaks or are unsure about the condition of your brake fluid, it is recommended to take your vehicle to a mechanic for a thorough inspection and necessary repairs. Ignoring this issue can lead to severe damage to your vehicle and pose a risk to your safety on the road.

How to Fix Flashing Brake Lights

Flashing brake lights can be a concerning issue, but fortunately, there are several steps you can take to fix the problem. Here’s a guide on how to address this issue effectively:

1. Check the Wiring System

Start by inspecting the wiring system of your brake lights. Look for any loose or damaged wires that may be causing the flashing lights. If you notice any issues, carefully reconnect or replace the damaged wires. It’s also a good idea to check the connectors and ensure they are securely attached. If you’re unsure about handling the wiring yourself, it’s best to seek assistance from a professional mechanic.

2. Check the Fuse

A blown-out fuse can also cause your brake lights to flash. Consult your car’s instruction manual to locate the fuse responsible for the brake lights. Once you’ve found it, carefully remove the fuse and check if it’s blown. If it is, replace it with a new fuse of the same rating. However, if the new fuse blows immediately or the flashing lights persist, it’s recommended to have a mechanic inspect the electrical system for any underlying issues.

3. Check the Bulbs

Dim or burnt-out brake light bulbs can also trigger flashing lights on your dashboard. To check the bulbs, have someone operate the brake pedal while you observe the rear of your car. If you notice any bulbs that are not functioning properly, replace them with new ones. Most bulbs are relatively easy to replace, but if you’re unsure, you can visit a service center for assistance. Remember to replace both bulbs if necessary. If the new bulbs don’t resolve the issue, it’s advisable to have a mechanic inspect the brake light circuit for any further problems.

By following these steps and addressing the potential causes of flashing brake lights, you can ensure the safety and functionality of your vehicle’s braking system. If you’re unsure or uncomfortable with any of the steps, it’s always best to consult a professional mechanic for a thorough inspection and repair.
