H4 HID Conversion Kits and Bulbs

Many vehicle manufacturers use H4 (also known as HB2 or 9003 bulbs) bulbs when their vehicle uses a smaller light housing. Halogen H4 bulbs serve as high and low beams and likewise our HID conversion kits have HID low beams and halogen high beams. Halogen bulbs operate at 55 watts and have an average life span of 1,000 hours of run time. HID bulbs operate 35 watts and can last 3-4 times longer.

To check what kit you will need for your car, please visit Sylvania's bulb replacement guide.

If you have a daytime running light (DRL) system on your vehicle, you will need to disable it or bypass it by tapping another 12v source like a parking light. Disabling a DRL system is different for every vehicle. To find information for your particular vehicle please browse LightsOut.org.
