What is the advantage of a HID system? Bottom line, HID headlights provide better visibility than ordinary halogen bulbs. The difference is even more evident during poor driving conditions. A significant percentage of road accidents take place during inclement weather, especially at night. HID lights allow drivers to overcome these conditions by providing up to 3 times more light. Added visibility contributes to driver confidence, which provides for a more relaxed, safer driver. What does our HID CONVERSION KIT include? All HID Conversion Kits include all necessary materials needed for installation. The Kit will include (2) Direct-Plug HID Bulbs (for perfect installation), (2) Ballasts, along with all necessary wiring. Most HID Conversion Kits are plug and play, which is perfect for clean and accurate installation. Why do I have to purchase the whole kit? Can I just buy the HID bulb? Motorcycles and automobiles currently use a 12 Volt electrical system for their headlamps. XENON HID lighting systems require over 20,000 volts to ignite the bulbs. Once lit, the bulbs require 12 volts or 9-15 volts to keep running. The kits include a power pack that is necessary for the lamps to turn on. The input of the power pack is 12 volts or 9-15 volts, depending on the brand. It is an integral part of the system. Wouldn't it be better for me to purchase a halogen bulb with higher voltage, instead of buying HID Bulbs? Remarkably, HID lights are able to provide greater light output with less power consumption. Studies show that a 35 Watt HID lamp produced 3 times as much light compared to a 55-Watt halogen bulb. Also, the 55-Watt halogen bulb uses a continuous power draw of 10-15 amps, while the HID system uses 20 for start-ups but drops to a mere 3 amps during operation. In addition to high output and low power usage, your HID headlight provides a longer service life. Under normal driving conditions, the bulbs will last approximately 4 years (3000 hours). That's up to 4 times as long as an ordinary halogen lamp. Increasing the wattage will make the bulb a little brighter but still much dimmer than the XENON HID lamps. This is critical in motorcycle applications. How long will these bulbs last? HID XENON lamps are designed to last for the life of your vehicle. They will run for over 2500 hours. Our lamp kits and bulbs are made of the finest materials available. Are Xenon H.I.D Light System street legal? Every country and jurisdiction has its own rules and regulations governing the use of automotive lighting. XENON H.I.D. lighting systems that are supplied with the vehicles from the factory are DOT / SAE approved. Our kits are also made by the same OEM manufacturers that supply all the major car installation. The Kit will include (2) Direct-Plug HID Bulbs (for perfect installation), (2) Ballasts, along with all necessary wiring. Most HID Conversion Kits are plug and play, which is perfect for clean and accurate installation.
