How to Fix a Car with a Malfunctioning Brake Light
One afternoon, I was driving down the highway when I noticed a vehicle behind me flashing its headlights. After a few moments, the driver honked, and I quickly pulled over to the shoulder. To my surprise, the person in the car behind me pointed at my brake lights, signaling that they weren’t working properly. At first, I was taken aback because I had no idea that something was wrong with my car. When I got out to check, sure enough, my brake lights weren’t lighting up when I pressed the brake pedal.
I had heard stories of malfunctioning brake lights, but I never thought I’d be dealing with them myself. Brake lights are essential for safe driving, and a malfunctioning brake light can be not only dangerous but also illegal. I realized that I needed to fix the issue immediately to avoid any potential accidents or legal problems. If you’ve ever found yourself in a similar situation, you know how important it is to resolve the issue quickly. In this article, I’ll walk you through the steps I took to fix my brake light, what might cause a malfunction, and how to diagnose and repair the issue yourself.

1. Understanding the Importance of Brake Lights
Brake lights are critical for safe driving, especially in heavy traffic or at night. When you apply the brakes, your car’s brake lights alert drivers behind you that you’re slowing down or stopping. This simple signal is crucial for preventing rear-end collisions. After realizing that my brake lights weren’t working, I understood just how much I relied on them for safety.
In addition to safety, malfunctioning brake lights can also lead to a traffic ticket. Law enforcement officers regularly check that vehicles have fully functioning brake lights as part of their routine traffic stops. Not having working brake lights is an immediate red flag for a violation, and I didn’t want to risk facing a fine or worse, an accident. This realization pushed me to take quick action.

2. Common Causes of Malfunctioning Brake Lights
The next step was to figure out why my brake lights weren’t working. I knew it could be one of several issues, so I set out to diagnose the problem. There are a few common causes of malfunctioning brake lights, which I quickly learned about:
- Burnt Out Bulb: The simplest cause of malfunctioning brake lights is a burnt-out bulb. I’ve had a similar experience in the past where a single brake light was out because the bulb was worn out. In most cases, this is an easy fix and involves simply replacing the bulb.
- Faulty Brake Light Switch: The brake light switch is responsible for activating the brake lights when you press the pedal. If this switch fails, the brake lights won’t turn on. I suspected this might be the issue when I checked the bulbs and they seemed intact, but the lights still didn’t come on.
- Blown Fuse: A blown fuse can also cause your brake lights to stop working. The fuse protects the electrical circuit that powers the brake lights. If the fuse blows, the circuit is interrupted, and no power reaches the brake lights. This is an easy fix by replacing the fuse, but I had to verify that this was the problem first.
- Wiring Issues: Another potential issue is damaged wiring, which can prevent power from reaching the brake lights. While this is less common, I’ve read about instances where frayed or disconnected wires caused brake light malfunctions. This was something I needed to inspect if the other options didn’t resolve the problem.
I knew that diagnosing the cause of the malfunction was the first step toward fixing it. I decided to go through each of these potential issues one by one to determine what the real problem was.
3. How to Inspect and Diagnose the Problem
I began my diagnostic process by checking the easiest possibility—burnt-out bulbs. I wanted to make sure that both the left and right brake light bulbs were intact. To do this, I opened the trunk of my car and accessed the brake light housing. This step is simple, and most car models allow easy access to the brake light bulbs.
I removed the brake light cover, inspected the bulbs, and found that one of them was indeed burnt out. Replacing a burnt-out bulb is one of the easiest car repairs, and I was relieved to find that the solution was relatively inexpensive. However, before I jumped to conclusions, I tested the other brake light to see if it worked. Unfortunately, it didn’t, either. I needed to look deeper.
The next step in my diagnostic process was to check the brake light switch. The brake light switch is typically located near the brake pedal, and I inspected it for any obvious signs of wear or malfunction. I found that the switch wasn’t functioning as expected. When I pressed the pedal, I didn’t hear the usual click that would indicate that the switch was activating the brake lights. This told me that the issue was likely with the switch, rather than the bulbs or fuse.
4. Replacing the Brake Light Bulb and Switch
Once I diagnosed that the brake light switch was the problem, I decided to replace it. Fortunately, this part was easy to find at the local auto parts store, and I didn’t need any special tools to remove and replace the switch. After disconnecting the battery (a safety precaution), I unscrewed the old switch and installed the new one. The process took less than an hour, and it was straightforward, even for someone like me who isn’t an expert mechanic.
After replacing the switch, I tested the brake lights again. This time, both lights came on as expected, and the issue was resolved. The feeling of satisfaction was immense—I had managed to diagnose and fix the problem myself, without needing to visit a mechanic or spend a lot of money.
5. When to Call a Professional for Help
While I was able to fix the brake light issue on my own, I understand that not everyone feels comfortable diagnosing or repairing car electrical problems. If you find yourself in a similar situation and aren’t able to fix the problem, it’s perfectly okay to seek professional help. There are a few signs that indicate you should call a professional mechanic:
- Complex Wiring Issues: If you’ve checked the bulbs, switch, and fuse but still can’t find the source of the problem, it might be time to call a professional. Wiring issues can be tricky to fix without the proper tools and knowledge.
- Persistent Malfunctions: If your brake lights continue to malfunction even after replacing the bulbs and switch, there could be a deeper issue with the car’s electrical system. A professional mechanic can use specialized diagnostic equipment to pinpoint the issue.
- Lack of Tools or Knowledge: If you’re unsure of how to proceed, it’s always safer to have a professional mechanic take over. Electrical components in your car can be delicate, and improper handling can lead to more damage.
I’ve found that knowing when to ask for help can save time and prevent further complications. If you're ever in doubt, don’t hesitate to call a professional.
6. Preventing Future Brake Light Issues
After fixing my brake light, I realized that maintaining the brake light system can prevent future issues. Here are a few maintenance tips that have helped me keep my brake lights working smoothly:
- Regular Inspections: I now check my brake lights regularly to ensure they’re functioning correctly. This simple step can save you a lot of time and effort down the road.
- Use Quality Parts: Using high-quality replacement parts ensures that your brake lights function properly for a longer period. I always make sure to use reputable brands when buying new bulbs or switches.
- Address Problems Early: If you notice any dimming of your brake lights or if they stop working intermittently, I recommend addressing the problem early before it becomes a bigger issue.
Keeping these tips in mind has helped me maintain my vehicle’s brake lights and avoid dealing with this issue again in the future.
