Upgrade your headlights and improve your night vision on the road with Kensun HID (High Intensitiy Discharge) Xenon headlights. Emitting a light that is 3 times brighter than ordinary halogen bulbs, HID lights greatly assist the driver in providing a clearer and expanded view of what is ahead. Subsequently, HID kits contribute to driver confidence, making for a more relaxed and safe drive. HID lights have a glass chamber of gas that replaces the filament of traditional halogen light bulbs. The gas is ignited with an approximately 23,000 volt charge and stays illuminated by a constant 12v source that is provided by a ballast which is connected directly to your battery. Remarkably, HID lights are able to provide greater light output with much less power consumption. Studies show that a 35 watt HID lamp produces 3 times as much light compared to a 55 watt halogen bulb. Moreover, the 55 watt halogen bulb uses a continuous power draw of 10-15 amps, while the HID system uses 20 amps for starting up, but then drops down to a mere 3 amps during operation (that is up to 80% less power during use!). In addition to high output and low power usage, the HID headlight provides longer service life. With no filament to vibrate and fatigue, under normal driving conditions, HID bulbs last roughly 10 times longer than halogen bulbs.
