Brake lights are among the most crucial lights on your vehicle. While most lights on a car are important for safety, brake lights serve a unique function: they act as a warning signal to drivers behind you. Without working brake lights, the driver following you may not know when you’re slowing down or stopping, which could lead to a rear-end collision. In addition to the safety risks, driving without properly functioning brake lights is illegal. To comply with roadworthy laws, all brake lights on your vehicle must work correctly at all times.
Given the vital role brake lights play in road safety, it’s essential to ensure they’re always in good working condition. If you experience issues with your brake lights, it’s important to have them checked and repaired by a professional auto electrician as soon as possible.
How Modern Brake Lights Work
In newer vehicles, brake lights are often connected to a circuit board, which allows each bulb to function independently. This means that if one brake light bulb burns out, the others will continue to work. This design ensures that even if a bulb fails, there will still be some level of warning for drivers behind you, though it’s still important to replace any non-functioning bulbs promptly.
Brake lights serve two primary purposes. The first is to provide low-intensity illumination when the car’s lights are turned on, such as during night driving. This low-level lighting lets other drivers know that your vehicle is in motion. The second, and perhaps more important function, is to increase in intensity when you press the brake pedal. This brighter light serves as a clear warning to the driver behind you that you’re slowing down or stopping.
The Role of the Third Brake Light
Many vehicles come equipped with a third brake light, often positioned above the rear window or on the rear spoiler. This brake light is typically even brighter than the standard brake lights located near the signal lights. The purpose of the third brake light is to increase visibility and draw even more attention to the fact that you’re slowing down or stopping. It comes on simultaneously with the other two brake lights, providing a triple warning to drivers behind you.
The addition of a third brake light has been shown to reduce rear-end collisions by improving the visibility of braking vehicles. This extra layer of safety is especially useful in heavy traffic or poor weather conditions when visibility may be reduced. As with your regular brake lights, it’s important to ensure the third brake light is functioning properly at all times.
Checking and Replacing Brake Lights
Brake light bulbs need to be replaced as soon as they burn out. There are several ways to check if your brake lights are functioning properly. One simple method is to have someone stand behind your vehicle while you press the brake pedal. They can then confirm whether all of the brake lights are illuminating correctly. Alternatively, you can park near a reflective surface, such as a garage door, and observe the reflection of your brake lights as you apply the brakes.
Some modern vehicles come equipped with light indicators on the dashboard that will alert you if a brake light bulb has failed. If your car has this feature, it’s a convenient way to stay on top of brake light maintenance without needing to manually check them regularly.
LED Brake Lights
Many newer vehicles are now equipped with LED brake lights instead of traditional incandescent bulbs. LED lights are smaller, more energy-efficient, and typically last much longer than standard bulbs. Because they use less energy and generate less heat, LED brake lights tend to be more reliable over time.
LED brake lights are often composed of multiple smaller lights, which work together to form a single brake light. If one LED fails, the others will continue to function, ensuring that you still have some level of visibility until the light can be repaired. However, it’s still important to have any malfunctioning LED lights replaced to maintain full functionality.
Brake Light and Signal Light Combinations
In some vehicles, the brake light shares the same lens as the signal lights. If this is the case, a dual-element bulb is used, with one element for the brake light and the other for the turn signal. In other vehicles, the brake light is positioned behind a red lens, while the turn signal may be behind a yellow or clear lens.
The third brake light, if present, is usually in the middle of the vehicle, away from the signal lights. Its distinct positioning helps it stand out and further alerts other drivers when you’re braking.
