what’s the use?
higher luminance low beam lamp and light exposure as compared distant. May provide greater illumination range when the difference between the road lighting conditions. Improve traffic safety. Usually high beam switch lever by adjusting the rear wheel.

Did you know?
· general urban road better lighting conditions, try to avoid using high beam.
· poor lighting conditions in the traveling road, the distance light can be used alternately, so as to impact on the vehicle dangerous sight.
* In addition to providing illumination, but also as far lights “lamp language” used, when necessary, to remind or alert the preceding vehicle.
· Do not turn on the high beam in case of foggy weather. Air fog poor transparency, the light is diffusely reflected, not only the illumination effect can not play it will affect vision.

The type of light source is divided into, halogen, xenon, LED , laser four.
halogen headlamps
is filled with a halogen element such as iodine, bromine, or tungsten halide lamps, usuallyCalled tungsten halogen lamp or a halogen lamp. Advantages of simple structure, low cost, easy to control brightness. Halogen headlights but low emission efficiency, a light source is not easy aggregation.
xenon headlights
is also called HID gas-discharge headlights. Instead of the traditional tungsten wire is wrapped with a high-pressure xenon gas into the quartz tube, providing higher color temperature, more gathered lighting. But compared to higher costs halogen headlights, the gas inside the need to reach a certain temperature emit light, a certain degree of hysteresis.
the LED headlamps
with a LED (light emitting diode) as a light source of headlights. The advantage of high reliability, and long service life. Simple rugged, less susceptible to shock impact, fast response. But its high cost, high heat during lighting, easily damaged.
Laser headlights
In a laser diode as a light source of vehicle headlamp, the LED headlamps as laser headlights have fast response speed, brightness, low attenuation, low energy consumption, long life . But smaller compared to the LED headlights, higher luminous efficiency.
