Headlight Pair For 18-21 Toyota Tundra RWD and 4WD Left and Right LED Headlamp

Halo lights are lights arranged in a ring around the headlights themselves. You've probably seen them on some cars, such as BMWs, where they are the factory option. In some cases the effect is achieved with bulbs, while on other vehicles it's done with fiber optics. Halo Lights can be a popular upgrade to make your car or truck stand out at night. Please be aware that most of theHalo lights we sell typically have to be manually wired up to your existing wiring harness. This is because your stock vehicle did not have Halos, and there is no wiring pigtail for them on the factory harness.

HID stands for "High Intensity Discharge". These bulbs use an electric arc rather than the glowing filament in a Halogen bulb. HID headlamp bulbs do not run on low-voltage DC current like a Halogen Bulb, so they require a ballast, which controls and regulates the flow of current. This ballast will require an ignitor to light the bulb. This is either integrated directly into the bulb or as a separate unit which is occasionally part of the ballast, similar to fluorescent bulbs in your home. In a vehicle, HID bulbs tend to be much more expensive to replace than a Halogen bulb.

Replacing stock Halogen headlights with HIDs would require some modifications, especially where the wiring is concerned. While the lamp can sometimes fit into the opening on the front of the vehicle, your stock lamps will use different bulbs, sockets, fuses, relays, and wiring than most HID bulbs. You may want to check with your local mechanic for advice if you have never attempted this type of conversion before.
