[WapCar] High-position brake light is generally installed on the trunk lid, on the top of the rear of the car or in the rear windshield, so that the cars driving behind can easily find the brakes of the cars in front, which can play the purpose of preventing rear-end collision.
The function of the high-position brake light is to warn vehicles driving behind to avoid rear-end collision. The vehicle without high-position brake, especially the sedans with lower chassis and mini cars usually don't have enough lightness when braking because the position of the rear brake light is lower, and it is sometimes difficult to see clearly the drivers of the vehicles following them, especially the trucks, buses and buses with high chassis, therefore the hidden danger of the rear-end collision is greater. A large amount of research findings prove that high-position brake light can efficiently prevent and reduce the rear-end collision. Therefore, high-end position brake lights are widely used in many developed countries.
