Usually a brake light mounted on rear of the vehicle, the main color is red light, the light penetration enhancement for traveling behind the vehicle even at a low visibility, easy to find a preceding vehicle brakes, serves to prevent collision accident the purpose occurred. Simple models is insured by the power, then the brake switch, the brake pedal for the brake, switch Unicom, two power is supplied to a brake lights and brake lights where the negative line connected to form a loop through the vehicle body.
1. The brake lamp classified by material
Depending on the material of the brake lights, brake lights can be divided into gas and LED brake lamps.
Gas brake lights, i.e., the material used is a gas, such as a halogen. Gas brake lights, mature technology, low cost, but will produce radiation, which contains mercury, the housing is made of glass, easily broken, resulting in environmental pollution.
LED brake lights, i.e., the material used is an LED. Made by the LED brake lights, no radiation, no pollution, long life, the theory reach 60,000 hours, that is to say, during a car is scrapped without changing a light bulb. However, the price of the expensive brake lights LED, therefore, itThe increasing use of the formation of a certain influence. In developed countries, LED brake lights have been widely used in China, the development of the past two years have begun to accelerate.
2. stop lamp classified by location
A is mounted on the rear ends of the brake lights, taillights belonging to the
One is the brake light, mounted on a vehicle end of the upper portion.
CHMSL
If you look closely, we have observed a square or rectangular red brake lights behind the middle of the high number of new car position. This lamp school called high brake lights, brake lights general than the tail on both sides of the car some distance above. Action CHMSL warning is traveling behind the vehicle, so as to avoid rear-end collisions. No high vehicle brake lights, especially the lower chassis of cars and mini cars, during braking position due to the lower rear brake lights, the brightness is usually not enough, which is followed by vehicles, especially high chassis trucks, buses and bus drivers sometimes difficult to see. Therefore, rear-end accident risks are greater. Numerous studies prove the findings, high brake lights can effectively prevent and reduce the incidence of rear-end accidents. Thus, high brake lights in many developed countries has been widely used. For example, in the United States, in accordance with regulatory requirements from the beginning of 1986, all new cars sold must be equipped with high-mounted stop lamp; from the beginning of 1994, all sales of light trucks also have to install brake light.

Press brake lamp base 3 Classification
1, P21 / 5W, or may also be referred BAY15D 1157, this base type brake light filament lamp has a double structure;
2, W21 / 5W, 7443 may also be referred to this type of brake lights of the base have a double filament structure;
3, P27 / 5W, 3157 may also be referred to this type of brake lamp base also has a double structure wire; [ 123] in general, the 1-3 brake lights for the vehicle rear seat, and includes a warning function shown bit, when in different functions, brake light power is varied. For example, P21 / 5W, warning function as power is 21W, as shown Bit while power is 5W.
4, W5W, or may also be referred to as a flat-line plug, the base model is W2.1 × 9.5d;
5, W16W, or may also be referred to as a flat-line plug, the base model is W2.1 × 9.5d;
Generally, the base brake lights for 4-5 brake light, the biggest difference is the head diameter of the brake lights, different power. General models with brake light W5W do, some models make use of W16W brake light.
4. The brake lights brake light image
automobile brake lights are part of a tail lamp, it is generally used in combination with the lamp inside the car. Whether the brake lights applicable, the key lies in whether the brake lamp base of automotive lighting design size requirements.
