APPLICATION: HID and LED bulbs are street legal in the USA for Fog Light use only. Not compliant with DOT / FMVSS108 and not street legal in the USA for Headlights. Legal for off-road use in Snowmobile and ATV headlights and off-road racing use only auxiliary or forward lighting. International street legality varies by country.

Note: This usage regulation is not unique to this item. All LED and HID bulbs from all other brands, regardless of marketing claims, are prohibited from street use in halogen headlights in the USA.



GTR Ultra HID Bulbs: Inserting HID bulbs into halogen designed H11 bases requires extreme accuracy. Each GTRLighting H11 HID bulb is laser aligned into its base so that the focal point of the HID bulb precisely matches the focal point position of the H11 halogen bulb, ensuring optically correct beam patterns. When you plan on installing this H11 HID bulb into your vehicle's fog lights, you can be certain that light is going to go where it's meant to be!

Ultra HID Bulbs: These Ultra HID bulbs are manufactured from high quality, German made Philips UV quartz glass to ensure you don't prematurely age your vehicle's fog lights. Many other HID bulbs use low grade glass that simply won't protect your vehicle's fog lights from the UV light HID bulbs emit. Each HID bulb will come with high quality insulated wires that will enable you to plug the HID bulb into a 35W or 55W-HID ballast (with AMP style connectors). You will also get additional wiring to connect your ballast into your vehicle's OEM fog light harness with a true matching connector, making this a proper plug+play application!

Lifespan: Average lifespan of these GTR Ultra HID bulbs is roughly 2500 hours--on par with OEM manufacturers such as Philips or Osram. These HID bulbs are sold in pairs to ensure your fog lights match in color as HID bulbs do color shift over time.
