High stop lamp
The current high level brake lamp is basically made of LED, which is because the LED high level brake lamp has the following advantages compared with the incandescent bulb high level brake lamp:
(1) The lighting speed is extremely fast (40~60ms), so that the response time of the subsequent driver is accelerated, the response time is 0.2~0.35 shorter than the original lamp, so the follow-up car parking distance is also shortened, which can improve driving safety (the parking distance can be shortened by 4.9~7.4m when the speed is 88km/h);
(2) High recognition. As we all know, red is a very bright color, whether during the day or at night, its visual stimulation of people far more than white, especially during the day, and red or people in the car to improve attention;
(3) Long life, its life is equivalent to 6 to 10 times that of incandescent bulbs;
(4) Resistance to vibration and impact. Because the LED high brake lamp has no filament, it is directly converted from electrical energy to heat energy, so it is resistant to vibration and shock;
(5) Save energy. Using leds to make car lights consumes far less electricity than incandescent lamps. According to analysis, the production of taillights with light-emitting diodes at night can save about 70% of electricity compared with incandescent bulbs, and can save about 87% of electricity for the production of high brake lights.
(1) For the driver approaching the following vehicle, even if he does not see the brake light of the vehicle in front, he can see the signal of the high brake light;
(2) When the front vehicle is a passenger car, even if the brake light of the vehicle moving further ahead is not visible, the operation information about the vehicle can be quickly learned because the signal of the high brake light is seen;
(3) For the driver of the subsequent car, the signal of the high brake light can give them general indication to prevent the occurrence of overtaking accidents.
Because the high brake light is installed above the brake light, and the light belt of the high brake light is relatively wide when it is made, mostly accounting for about half of the rear window, it is easy to be found by the driver of the follow-up car, the alarm effect of the follow-up car is good, and the response ability of the driver of the follow-up car can be greatly improved, so as to ensure the driving safety of the follow-up car.
Brake system problems: abnormal sound of high brake lights and braking occurs, which is a problem of the brake system, such as brake pad wear or insufficient brake oil, etc., which needs timely maintenance.
It seems to you that this situation is mainly caused by the unstable fixing of the brake light, which can be removed and fixed again.
The abnormal sound when braking is nothing more than the hard spot on the brake pad, and it is necessary to check whether there is rust on the brake disc, which will also lead to obvious sound.
There are different solutions according to different sounds: if it is screaming, the first thing to check is that the brake pad is running out (alarm sheet sound). If it's a new film, check to see if there's anything caught between the brake disc and the disc. If it is a dull noise, it is mostly a problem with the brake caliper, such as the wear of the movable pin, the spring sheet falling off, and so on.
