Understanding the Importance of a High Mounted Brake Light: How it Works, Benefits, Cost, and Installation

Introduction

The high mounted brake light, also known as the third brake light, is an essential safety feature in modern vehicles. This additional brake light is mounted higher than the traditional two brake lights, typically on the rear windshield or the rear spoiler. It was first introduced in 1986 by General Motors and has since become a standard feature in all vehicles. In this article, we will dive into the details of how the high mounted brake light works, its benefits, cost, installation process, common symptoms of malfunction, comparison with traditional brake lights, and the best brands in the market. We will also provide maintenance tips and real-life examples to support our discussion. So, let's get started!

How it Works

The high mounted brake light works in conjunction with the traditional two brake lights to provide an added layer of safety. When the brake pedal is pressed, the brake light switch is activated, sending an electrical signal to the brake lights to turn on. This signal also activates the high mounted brake light, which lights up simultaneously with the traditional brake lights. This additional brake light is strategically placed higher to ensure that it is visible to drivers behind the vehicle, even if they are following too closely.

The high mounted brake light is usually a single light unit with a red lens cover. It can have a single bulb or multiple bulbs, depending on the vehicle's make and model. In most cases, the high mounted brake light is connected to the same electrical circuit as the traditional brake lights, ensuring that they all light up when the brake pedal is pressed. However, some vehicles may have a separate circuit for the high mounted brake light, allowing it to function independently in case of a malfunction in the traditional brake lights.

Benefits

The high mounted brake light provides several benefits for both drivers and pedestrians. Let's take a look at some of the most significant benefits:

Safety

The primary benefit of the high mounted brake light is the added safety it provides on the road. By being placed at a higher position, it increases the visibility of the vehicle's braking action, especially in low visibility conditions such as heavy rain, fog, or night driving. This extra visibility can help prevent rear-end collisions, reducing the risk of accidents and injuries on the road.

Decreased Stopping Distance

Studies have shown that the high mounted brake light can decrease the stopping distance of a vehicle by up to 16 feet. This is because the added visibility of the high mounted brake light allows for faster reaction time for drivers behind the vehicle, giving them more time to brake and avoid a collision. This can be particularly useful in high-speed situations or when driving on busy highways.

Improved Fuel Efficiency

The high mounted brake light can also contribute to improved fuel efficiency. By reducing the risk of rear-end collisions, it can help prevent sudden braking, which can waste fuel. This is especially true for stop-and-go traffic situations where frequent braking and acceleration can significantly impact fuel consumption.

Cost and Price

The cost of a high mounted brake light can vary depending on the make and model of the vehicle. On average, the cost of a replacement high mounted brake light can range from $20 to $100. However, the installation cost can add up to the total expense, as it may require professional assistance. The cost of installation can range from $50 to $200, depending on the labor rates of the mechanic and the complexity of the installation process.

If you need to replace the high mounted brake light on your vehicle, it is essential to consider the cost and compare it with the potential benefits it can provide. Remember, this safety feature can save you from costly repairs and medical expenses in case of an accident.

Installation

The installation process of a high mounted brake light may vary depending on the vehicle's make and model. In general, it involves removing the old high mounted brake light, connecting the new one to the wiring harness, and mounting it in the designated spot. However, some vehicles may require additional steps, such as removing interior panels to access the high mounted brake light housing.

While it is possible to install a high mounted brake light on your own, it is recommended to seek professional help to ensure proper installation and avoid any potential damage to the vehicle. Mechanics have the necessary tools and expertise to install the high mounted brake light correctly, ensuring its proper functioning.

Symptoms of Malfunction

As with any other vehicle component, the high mounted brake light can also malfunction over time. Here are some common symptoms that indicate a malfunctioning high mounted brake light:

• The high mounted brake light does not turn on when the brake pedal is pressed.
• The high mounted brake light flickers or remains dim when activated.
• The high mounted brake light remains on even when the brake pedal is not pressed.
• The high mounted brake light does not turn off, even after the engine is turned off.

If you notice any of these symptoms, it is important to get your high mounted brake light checked by a professional mechanic. A malfunctioning high mounted brake light can compromise your safety on the road and should be addressed immediately.

Comparison with Traditional Brake Lights

One of the most common questions about the high mounted brake light is its comparison with traditional brake lights. While both serve the same purpose of indicating that the vehicle is braking, there are a few key differences between them:

Placement

The most significant difference between the high mounted brake light and traditional brake lights is their placement. The traditional brake lights are located on the rear of the vehicle, while the high mounted brake light is placed higher, typically on the rear windshield or the rear spoiler. This placement provides added visibility for the high mounted brake light, making it easier for drivers behind to spot it.

Number of Bulbs

In most cases, the traditional brake lights have two bulbs, while the high mounted brake light can have a single bulb or multiple bulbs, depending on the vehicle's make and model. This difference is due to the high mounted brake light's primary purpose to provide added visibility and not to act as the primary brake light for the vehicle.

Functionality

The traditional brake lights and high mounted brake light function differently. The traditional brake lights are connected to the brake pedal, while the high mounted brake light can have a separate circuit that activates it when the brake pedal is pressed. This functionality ensures that the high mounted brake light can still function even if there is a malfunction in the traditional brake lights.

Pros and Cons

Like any other vehicle component, the high mounted brake light comes with its own set of pros and cons. Let's take a look at them below:

Pros

• Increased safety on the road
• Decreased stopping distance
• Improved fuel efficiency
• Can function independently in case of malfunction in traditional brake lights

Cons

• Additional cost for replacement and installation
• Potential for malfunction and added maintenance
• May not be as effective in certain weather conditions, such as heavy snow

Best Brands

When it comes to purchasing a high mounted brake light, it is important to choose a reputable brand to ensure quality and reliability. Some of the best brands in the market for high mounted brake lights include:

• Philips
• Sylvania
• ACDelco
• Bosch
• Wagner

Make sure to do your research and compare prices and reviews before making a purchase decision.

Maintenance

To ensure the proper functioning of your high mounted brake light, it is essential to perform regular maintenance. Here are some tips to keep in mind:

• Check the high mounted brake light regularly to ensure it is working correctly.
• Replace any burnt out bulbs immediately.
• Clean the high mounted brake light lens regularly to ensure maximum visibility.
• If you notice any signs of malfunction, get it checked by a professional mechanic.
