Headlights Pair Fits GMC Terrain Denali 2013-2015 CAPA Certified Left Driver and RIght Passenger Headlamp Set

These types of lights used to be more popular on most European vehicles, but are becoming common on other makes and models. Projector lights are lights that have a filament located at one focus of a reflector, and a round glass or heavy duty plastic condenser lens at the front of the lamp. These lenses in front of the light bulb distribute the light evenly across the front of the vehicle, and can give a larger range of visibility for the driver. The bulbs themselves are usually common Halogen bulbs that can easily be changed.

Installing new headlights on your vehicle can result in fitment issues if they are improperly installed. Many times an alignment post is not inserted correctly, or a bracket is not tightened to the correct torque. In other cases, the incorrect part is being installed. We want to know if you have any installation issues with your new parts as soon as possible, so that we can help you figure out exactly what is wrong. Please contact us so we can help you save time with any questions you might have if something does not appear to fit correctly..

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.
