Early Development and Adoption
The concept of a third brake light dates back to the 1960s, when it was first introduced as an optional feature in some vehicles. Initially, it was met with skepticism, and its adoption was slow. However, as the importance of road safety became more apparent, the third brake light gained popularity, and its use became more widespread.
One of the earliest adopters of the third brake light was the General Motors company, which introduced it as an optional feature in the 1960s. The third brake light was initially placed at the top of the rear window, but its placement varied depending on the vehicle model.
The third brake light gained more attention in the 1970s, when it became a requirement in some countries. In 1972, the United States introduced a regulation requiring all new vehicles to be equipped with a third brake light. However, this regulation did not specify the placement or design of the third brake light.
International Adoption
The adoption of the third brake light was not limited to the United States. Other countries, such as Canada and Europe, also introduced regulations requiring the use of third brake lights. In 1974, the European Economic Community introduced a regulation requiring all new vehicles to be equipped with a third brake light.
The third brake light became a standard feature in many countries, with its placement and design varying depending on the vehicle model and country of origin. In some countries, the third brake light was placed at the top of the rear window, while in others it was placed at the bottom of the rear window or even integrated into the rear bumper.
Design and Placement
The design and placement of the third brake light have undergone significant changes over time. Initially, the third brake light was a simple red light, but it has evolved to include more complex designs and features. Some vehicles feature a third brake light that is integrated into the rear window, while others feature a separate third brake light that is placed at the top or bottom of the rear window.

The placement of the third brake light has also varied depending on the vehicle model and country of origin. In some countries, the third brake light is placed at the top of the rear window, while in others it is placed at the bottom of the rear window or even integrated into the rear bumper.
Regulations and Standards
The regulations and standards governing the use of third brake lights have evolved over time. In the United States, the National Highway Traffic Safety Administration (NHTSA) is responsible for setting safety standards for vehicles, including the use of third brake lights.
The NHTSA has introduced several regulations and standards governing the use of third brake lights, including:
- The use of a third brake light as a standard feature in all new vehicles.
- The placement of the third brake light at the top of the rear window.
- The use of a red light for the third brake light.
- The use of a LED or incandescent bulb for the third brake light.
Impact on Road Safety
The third brake light has had a significant impact on road safety. By alerting other drivers of the vehicle’s intentions to slow down or stop, the third brake light has reduced the risk of accidents and improved overall road safety.
A study by the National Highway Traffic Safety Administration found that the use of third brake lights has reduced the risk of rear-end collisions by 17%. Another study by the Insurance Institute for Highway Safety found that the use of third brake lights has reduced the risk of fatal rear-end collisions by 10%.
Year of Mandatory Adoption
The year in which the third brake light became mandatory varies depending on the country. In the United States, the third brake light became mandatory in 1972, when the National Highway Traffic Safety Administration introduced a regulation requiring all new vehicles to be equipped with a third brake light.
In other countries, the mandatory adoption of the third brake light occurred at different times. In Canada, the third brake light became mandatory in 1974, while in Europe, it became mandatory in 1976. (See Also: Clicking Sound When I Brake? Don’t Ignore It!)
