LED brake light is also installed in the rear of the car, switch of which connected with brake pedal by circuits. Treading the brake pedal can cause its lighting up. Since the main object of this light is warning other vehicles in the rear side of user’s car, the light intensity of this kind of LED lights in relatively high compare with other external LED vehicle lights only performing display operation. In order to avoid the rear-end collision caused by large vehicles, high mounted brake light made up of linear arrayed LEDs (similar to LED bar).

The LED turn signals (1W-3W) of cars are usually installed on both side of the front and the rear, indicating (flash light) the driving trend of the car. The flash frequency of this light is around 50Hz. Run-up time is less than 1.5s. When in a emergency needs to draw other vehicles’ attention, all of the four LED turn signals can be switched on simultaneously, constantly flashing.

LED position lamps, also known as “width lamps”, are installed in the front/side/back of the car (an auxiliary vehicle light different from side lights). When users driving during the night, headlight, position light, instrument-panellamp and license plate light will send out light simultaneously. The main usage of LED position lamps is indicating the form of the car for other pedestrians and vehicles. LED position lamps are not as important as other main external LED vehicle lights, like LED headlights and LED turn signals. The brightness requirement of it is thus lower (only 0.5W-2W). Generally, white/yellow for head position lamps, red for tail lamps and amber for side position lamps.

LED warning lights and LED street light can be used in certain special conditions. Because of its particularity, it is not a necessary for each vehicle. LED warning lights (5W-10W) are generally installed in the top of the car. Different color represents different type of vehicles: red used by police car, blue represents ambulance, bus and taxi always use white or yellow. All of these LED warning lights have a common flash frequency of 2-6 per second. LED warning lights are a kind of unusual external LED vehicle lights. For a seek of convenient administration, this light is even forbidden to common users in some countries.

LED high bay day running lights is another unusually used external LED vehicle lights. They are seated in the head of the car, making the car can be easily recognized during the day. They are as much really a decorative light as a functional light. The largest usage for this light is to make the car look more awesome.

Common external lights for vehicles are: headlights, for LED lights, license plate lights, reversing lights, brake lights, turn signal indicator lights, marker lights, etc. The generally used color for external vehicle lights is white, orange yellow and red. Vehicles performing special tasks (fire engines, police cars, ambulances, emergency rescue vehicles) usually use red, yellow and blue flash caution lights for the purpose of first pass. Nowadays, LED lighting Products technology has been generally applied in the vehicle lighting. The common external LED vehicle lights can be classified as follow:

Head lamp is commonly known as “head light”, mounted on the front of the car, used to illuminate the road. According to different purposes, they also can be classified as high beam headlights (40W-60W) and dipped beam headlights (35W-55W). White high brightness LED headlight is a good substitute for normally used filament lamp, halogen lamp and high intensity discharge lamp (HID). Presently, they have become the main external LED vehicle lights.

Fog lights are usually installed in the front side and in the end side of the car. In the case of fog, snow, rain and dust, fog lights can be used to improve the lighting performance of the headlights. They can be treated as auxiliary lighting tools. Since the lamp flux requirement for fog lights is not so high (3W-5W orange yellow for head fog lights and 3W-5W red for tail fog lights), they can be simply replaced by LED spot lights with relatively low power consumption.

LED license plate lights are mounted on the rear of the car, on the both side of the license plate. Similar to LED fog lights, since the power consumption is just 1W-2W (ensure the words and figures can be recognized within 20 meters), LED spotlights are fully available for using purpose.

LED reversing light is installed in the rear of the car, automatically lighting when the transmission hung in reverse. As well as lighting up the rear side of the car, it also can warn pedestrians and other vehicles at that position. LED reversing light has a relatively higher requirement in beam angle (larger than commonly used small external LED vehicle lights), as a result of providing users with a larger visual field behind the car, consequently increasing the safety factor. The generally used LED reversing light has a power consumption of 2W-5W, white color.
