LED Car light
LED car light is referred to using LED (light emitting diode) lights as the light source. For LED with high brightness, color variety, low power consumption and long life characteristics, LED is widely used in automobile industry.
1. External light type
Common external lights: headlamps, fog lamps, license plate lights, reversing lights, brake lights, turn signals, position-indicating lights, clearance lamp, parking lights and warning lights and daytime running lights, The external light color of performing special tasks vehicles is generally white, orange, yellow and red; Such as fire engines, police Cars, ambulances, emergency rescue vehicles, Using has a priority right of passage for the red, yellow or blue flashing warning lights.

Before the 2011 Europe compulsory motor vehicle daytime running lamp, LED will be more widely used in automobile.
2 .Types of interior lights.
The common internal lamp has a lamp, reading lamp, luggage compartment lights, lantern, stoplight, instrument lights, work lights, instrument panel alarm indication lamp.
(1) Lamps for cars and trucks are generally set up a lamp, except for car interior lighting, can also be used to monitor whether the door closing. Under the monitoring door state, as long as there is no reliable door shut, the lamp shines. Power is generally 0.5-2W, bus lamps have to fluorescent lamp development trend.

LED lights to light-emitting diodes directly by the electrical energy into light energy, equivalent to only 1/10 of the traditional lamp bulb power consumption compared with ordinary cars, saving fuel consumption, protect the car circuit is not burned out by excessive load current.
