For the past 40 years, light-emitting diodes have been successfully employed wherever small amounts of light are needed. Present-day applications includecar led liight of led signal light reversing and car led brake light , car led license plate light,car top light, led strip light.
 
With the improvement of the socity and the electronic control system,the appearance of the new type,high grade led car light,the canbus led light has is shining. When the dashboard need use it,it can use it directly from Engine ECU.Then it can save more  sensor and cable.It’s appearence slove the problem of  waisting cable and difficullt work to design the complex circuit.It let people believe that can control many unit at the same time,then can save more sensor and cable quantity. With car led bulb of canbus system  in the car,we just need to put the signal,if the signal is use the EFC connect the Engine ECU. According to the carmaker, the auto marks a key function with error cancellor.It mainly used in the new type of Audi,BWM, Benz. Also now with the( cotroller Area Network-BUS) canbus, it is also the judgement of whether a car is “ digitization”.
Now in the market,this car led bulb of canbus light is mainly use the 2W,5W to design,it’s merit is decrease the wiring harness and the pin quantity of at the connector of the controller .Meanwhile it can realize online Program ,online diagnose,it even can work with many controller at the same time.Now with the recent need,canbus led is more and more advancing,still advancing with the demend. The car led light includes a range of technology designed to advance the vehicle’s function and light for the user.It is more safer and advancer. With less impact on the enviroment, good vibration and steable emitting.
