      If the front of your vehicle is its “face”, then the headlamps have long been considered the vehicle’s “eyes”. Everyone notices them. One of the most distinctive changes you can make to the face of your car or truck is to replace the factory headlamp assemblies with a custom set. Your ride will take on a personality all its own, and will gain a distinctive appearance that will set it apart from all the other look-alike vehicles on the road.

      We at CARiD know that there are times when you need to replace factory headlight assemblies with units that match the quality and function of your originals. While it's more "fun" to customize your ride, sometimes the repair takes priority. One headlamp lens may be cracked. You may have been in a minor fender-bender (lamp bender?) and the mounting tabs may have broken. Note that "factory" style headlight assemblies we sell are designed to replicate the original lamps, so you will not be considering features such as LEDs, halo rings, or projector beams. We've created this article to help ensure what you purchase is exactly right for your needs and wants.

      Custom headlamp assemblies on the market today tend to be grouped into four main designations: "Projector" style, "Halo" style, "LED" style, and "Euro" style. This can lead to confusion, because "Halo" style headlamp assemblies may also be equipped with projector lights and LED bulbs. Or, "Euro" style headlight assemblies may be equipped with halo rings, projector lights, and LEDs… or they may not be. You may be asking yourself which style is the best choice for me? See our Custom and Factory Headlight Glossary for definitions and more details about each style.

      Those of you born after 1990 or so have grown up in an automotive world where “all cars” have composite headlamp assemblies, uniquely designed to be make- and model-specific. If a light within the assembly burns out, you replace “just” the bulb. If the unit cracks, you must purchase a replacement that fits your car and your car only.

      When searching for a new set of headlamp assemblies for your ride, you may come across any number of terms which require explanation. Like many other accessory categories, headlamps use their own terminology. For your convenience, we provide you with this list, presented in alphabetical order, and with photos to help you identify these features.

      Ever since BMW introduced "halo" headlights to serve as daytime running lights on their 2001 5-series, rings of light encircling round headlamp bulb openings have caught on around the world as THE dramatic way to add visual Wow and stance to a vehicle's front profile. While composite headlamp assemblies became mainstream in the 1980s, it wasn't until the turn of the millennium that automakers began to style multi-faceted projector beam style bulbs within the housings.

      There is now LED lighting technology available for every conventional automotive lighting purpose. The incandescent bulbs haven’t really developed that much in the 140 years they have existed, while the development rate of LEDs is very rapid, with LED performance being doubled every 36 months, a development rate that is similar to the fast pace of computer development.
    • Automotive Lighting
      Today, halogen bulbs are most often used for headlights and fog lights, and their increased light output increases driver visibility in darkness and inclement weather. Halogen bulbs are a variant of the traditional incandescent bulbs that have been used since the early days of the electric light. The bulb is either evacuated (has a vacuum) or filled with an inert gas to keep the filament from oxidizing.

    Spyder Headlights for GMC Sierra
    The headlights look great, especially compared to the stock lights that were 15 years old in my GMC Sierra. The headlights installed very easily due to GMC engineering. The plastic frame structure that holds the lights and the adjustment screws is more flexible than the OEM product. So far it does not appear to be an issue, time will tell. The price for both headlights and the daytime running light with blinker combo was hard to pass up.
