What are car high brake lights
automotive high brake light is a kind of brake light installed on the upper part of the rear of the car, its main function is to remind the rear vehicle to pay attention to the braking situation of the vehicle in front, so as to avoid the occurrence of rear-end accident. The high brake light is often referred to as the third brake light because most vehicles already have two brake lights at each end of the rear, one left and one right, and the high brake light is located in the upper rear, forming the third brake light .
The working principle of the high brake light is that through the reflection principle, the light-collecting envelope Angle of the light-emitting diode (LED) is almost reached the entire spherical divergence Angle, so as to maximize the radiation effect of the tube core. This design makes the high brake light in the upper part of the car can be found earlier by the rear vehicle, especially in the case of high-speed driving such as highways, which can effectively prevent rear-end accidents .
The high position of the brake light makes it more visible in the traffic flow, especially for vehicles with higher chassis such as trucks, buses, etc., which are easier to be found by the rear vehicle. In contrast, ordinary brake lights may not be bright enough due to their low position and are easy to be ignored .
In addition, high brake lights usually use LED technology, which has a longer service life and higher brightness, further enhancing their warning effect .
The main function of high brake lights is to warn vehicles behind, so as to avoid traffic accidents . The high brake light is usually installed above the rear window of the vehicle. Due to its high position, the rear vehicle can observe the braking behavior of the front vehicle more clearly, so as to make appropriate responses, and effectively prevent the occurrence of rear-end collision .
The design principle of the high brake light is that through its high position, it is easier for the rear car to detect the braking action of the front car. These lights are not only installed on the trunk lid, the rear roof, but also commonly on the rear windscreen, and their main task is to warn the rear car to avoid rear-end collision .
The high brake light, together with the traditional brake lights on both sides of the rear of the vehicle, constitutes the vehicle's brake indication system and is commonly referred to as the third brake light or high brake light .
Vehicles without high brake lights, especially small cars and subcompact cars with lower chassis, have safety risks when braking due to the low position and insufficient brightness of traditional brake lights. Therefore, the addition of high brake lights provides a more obvious warning for vehicles behind, further enhancing driving safety .
The main reasons for the failure of high level brake lights in automobiles include the following :
brake bulb failure : the brake bulb may be aged or damaged, and the bulb needs to be inspected and replaced .
line fault : There may be problems with the line of the brake light, including poor contact or open circuit. It is necessary to check that the line is firmly connected to eliminate potential line faults .
not applying the brake pedal : the high brake light will only light up when the brake pedal is pressed down. If the brake pedal is not pressed down, the high brake light may not light up .
faulty brake light switch : the brake light switch may be faulty. Check and replace the brake light switch .
blown fuse : The line insurance may have blown, causing the brake lights to not work properly, need to check and replace the fuse .
Self-inspection and maintenance methods :
Check brake light fuses : When driving or igniting, check the brake light fuses for burnout .
Check the light bulb and wiring : open the trunk, locate the high brake light, check whether the light bulb is damaged or poor contact, and whether the cable is loose or broken .
Check brake pedal : if the high brake light does not come on after the brake pedal is pressed down, check that the brake pedal is pressed down correctly .
Use a test lamp or multimeter : Use a test lamp or multimeter to check whether the circuit of the high brake lamp is powered on. If the circuit is interrupted, repair the circuit .
Preventive measures and routine maintenance :
Regularly check the bulb and wiring : Regularly check the bulb and wiring of the high brake light to ensure that they are working properly .
Keep the vehicle clean : to avoid damage to the internal lines of the vehicle due to accumulation of debris, keep the interior of the vehicle clean .
