XTR HID:Inserting HID bulbs into halogen designed H4 bases requires extreme accuracy. Each XTR H4 HID bulb is laser aligned into it’s P43t (H4) so that the focal point of the HID bulb precisely matches the focal point position of the H4 halogen bulb – Ensures optically correct beam patterns. Whether you plan on installing this H4 HID bulb into your vehicle’s headlights or fog lights, you can be certain that light is going to go where it’s meant to be!
QUALITY THROUGHOUT:XTR H4 Xenon bulbs are manufactured from high quality, German made Philips UV quartz glass to ensure you don’t prematurely age your vehicle’s headlights. Many other H4 HID bulbs use low grade glass that simply won’t protect your vehicle’s headlights from the UV light HID bulbs emit – low quality H4 HID bulbs will damage your vehicle’s headlights. Each H4 HID bulb will come with high quality insulated wires that will enable you to plug the H4 HID bulb into a 35W-HID ballast (with AMP style connectors). You will also get additional wiring to connect your ballast into your vehicle’s OEM H4 headlight harness with a true H4 connector - plug+play application!.
LIFESPAN:Average lifespan of these H4 HID bulbs is roughly 2500 hours – on par with OEM manufacturers such as Philips or Osram. These H4 HID bulbs are sold in pairs to ensure your H4 HID headlight bulbs match in color – HID bulbs do color shift over time. True color match, accurate beam patterns, and quality components – don’t sacrifice when it comes to your vehicle’s lighting. H4 HID bulbs replace the following halogen fitments: H4, 9003
