Xenon Headlights

Xenon headlights make night driving safer and easier because they shine further than standard halogen lights. In addition, their clear blue-white light is more like daylight and less tiring for your eyes. They light up more of the road and verge, increasing your night vision. The xenon bulbs use less energy and generally last longer than conventional headlamp bulbs, however, this will be dependant on driving conditions and vehicle use. Xenon bulbs should only be replaced by a qualified technician. The source of light is a gas-discharge lamp. An arc-over between two electrodes in the xenon-gas atmosphere in the lamp bulbs results in an ionized gas tube through which electric current flows. This causes the gaseous mixture to glow in the form of an electric arc. A sophisticated electronics system is needed to operate these bulbs in order to generate the high ignition voltage of between 18,000 and 30,000 volts. This guarantees constant operation at an output of just 35 watts or automatic reignition.
