HID bulbs also shine much brighter due to this technology. Longer Life: The HID Kit lasts over 4,500 hours over 8 times more than OEM halogen bulbs. Safety : HID Xenon bulbs have an increased brightness of 300% (over traditional halogen bulbs) adding an extra margin of safety. Appearance: the HID Kit produces comfortable light which is very close to the natural light emitted by the sun. It makes everything easier to see at night.
