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.
