Premium 35W H4-2 Hi/Low replacement HID bulb for aftermarket H4 HID conversion kits. This bulb has a Xenon Low beam and a Halogen Hi beam. This bulb does require a special relay to function the high beam. If you already have a kit using H4 bulbs and simply need replacement, these are for you.
We always recommend to buy two bulbs instead of one. The HID bulb is charged with Xenon gas which burns out slowly affecting bulbs brightness and colour. With only one replaced bulb vehicles dipped beam will have two different colours.
All Our products are E marked and safe to use. Outer cover is UV-CTU ultraviolet quartz glass which prevents damage to plastic lens.
