When driving at night strong light glare

2、s into the driverseyes due to meeting each other halfway with the car lights on and the road reflection which may cause the drivers to see the road ahead unclearly. 32.In this case the drivers need to manually switch the type of the carsheadlights in time. But sometimes the drivers dont have enough

3、time to accomplish that action .which results in traffic accidents.For this we designed the Auto Switching System for Vehicle Headlights.4Objective: First: automatic converter is a kind of used in the car when driving at night .Second: It can be automatically finished in the 50 to 100 metres high be

4、am into a low beam lights.5Third: Back after the meeting and can quickly return to high beam illumination of the automobile high beam, low beam lights automatically transform device. Fourth: Use of program control motor and reversing, to realize the shade different Angle! Realize the distance light
