How the 3rd Brake Light Works: Benefits, Cost, Price, Installation, and Maintenance
The Importance of the 3rd Brake Light
The 3rd brake light, also known as the center high mount stop lamp (CHMSL), is an essential safety feature in vehicles. It is a red light located at the center of the rear windshield or above the rear window. This additional brake light provides extra visibility to other drivers, making it easier for them to see when you are braking. This is especially important in situations where the driver behind you may not be able to see your traditional brake lights, such as in heavy traffic or during inclement weather.
While the 3rd brake light has been a standard feature in most vehicles since the 1980s, it wasn’t until 1994 that it became a requirement by law in the United States. The National Highway Traffic Safety Administration (NHTSA) mandated that all new cars must have a CHMSL to improve road safety.
How the 3rd Brake Light Works
The 3rd brake light works in conjunction with the traditional two brake lights, creating a triangle of light that is more noticeable to other drivers. When the brake pedal is pressed, the electrical current from the brake light switch travels to the 3rd brake light, causing it to illuminate. This additional brake light is typically brighter than the traditional brake lights, making it easier to see from a distance.
Benefits of the 3rd Brake Light
- Improved visibility: The primary benefit of the 3rd brake light is that it provides better visibility to other drivers on the road. This is especially important in situations where the traditional brake lights may not be as visible, such as during heavy traffic or inclement weather.
- Reduced risk of rear-end collisions: Rear-end collisions are one of the most common types of accidents on the road. The 3rd brake light helps to reduce the risk of these accidents by providing an extra warning to drivers behind you that you are braking.
- Compliance with safety regulations: As mentioned earlier, the 3rd brake light is mandated by law in the United States. By having this feature in your vehicle, you are ensuring that you are compliant with safety regulations and doing your part to make the roads safer for everyone.
Cost and Price of the 3rd Brake Light
The cost and price of the 3rd brake light can vary depending on the make and model of your vehicle. On average, the cost of a replacement 3rd brake light can range from $50 to $200. However, if you are looking to install a 3rd brake light on a vehicle that does not already have one, the cost can be significantly higher. This may involve purchasing additional wiring and components, which can add to the overall cost.
Additionally, the price of installation can also vary depending on the type of vehicle and the complexity of the installation process. It is recommended to have a professional mechanic install the 3rd brake light to ensure it is done correctly and to avoid any potential electrical issues.
Installation of the 3rd Brake Light
The installation process for a 3rd brake light will depend on the make and model of your vehicle. Some vehicles may already have the necessary wiring in place, making the installation process relatively simple. However, for vehicles that do not have a 3rd brake light, the process can be more complex.
In most cases, the 3rd brake light will need to be wired into the existing brake light circuit. This may require additional wiring and modifications to the vehicle’s electrical system. It is recommended to have a professional install the 3rd brake light to ensure it is done correctly and to avoid any potential issues.
Symptoms of a Malfunctioning 3rd Brake Light
Like any other vehicle component, the 3rd brake light can malfunction over time. Some common symptoms of a malfunctioning 3rd brake light include:
- The 3rd brake light does not illuminate when the brake pedal is pressed.
- The 3rd brake light stays on constantly, even when the brake pedal is not pressed.
- The 3rd brake light flickers or flashes.
If you experience any of these symptoms, it is important to have your 3rd brake light checked and repaired by a professional mechanic. A malfunctioning 3rd brake light can compromise your safety on the road and may result in a traffic violation.
