Headlights & Assemblies

Filter By:

Headlights and assemblies are essential components of a vehicle’s lighting system, providing visibility and safety during nighttime driving or in low-visibility conditions. Headlights are typically composed of bulbs, reflectors, and lenses that work together to illuminate the road ahead, allowing drivers to see clearly and be seen by others. Modern headlights come in various technologies, including halogen, HID (High-Intensity Discharge), and LED (Light Emitting Diode), with LED headlights becoming increasingly popular due to their energy efficiency, brightness, and longer lifespan. Headlight assemblies are the entire housing unit that holds and protects the bulbs and other components, ensuring they stay secure and functional.


Headlight assemblies not only house the lighting components but also include other important features like adjustable beams, which allow drivers to control the height and direction of the light to prevent glare for other drivers. These assemblies are designed for easy replacement and come in a variety of styles to match different vehicle models. Over time, headlights and assemblies may need to be replaced due to wear, damage, or diminished light output. In addition to providing essential illumination, a properly functioning headlight system also enhances the vehicle’s overall appearance and ensures compliance with safety regulations. Whether you are upgrading to brighter, more efficient lights or replacing worn-out components, headlights and assemblies are crucial for maintaining safe driving conditions.


Frequently Asked Questions

Start with Select Your Vehicle on OmniGarage. Then check which factory headlight system your vehicle has, especially if it was offered with more than one configuration.

A headlight may fit the same year and model but require different connections depending on whether the vehicle originally had halogen, HID, LED reflector, or LED projector headlights. Some aftermarket assemblies require a specific converter for the factory lighting configuration. AlphaRex, for example, uses different converters for certain factory LED reflector and LED projector systems.

Choose based on the result you want, not on which technology sounds more advanced.

OEM-style assemblies make sense when you want a factory-like appearance and configuration. Projector, LED, halo, and other aftermarket assemblies make more sense when you intentionally want a different lighting design or appearance.

OmniGarage carries all of these styles, so first narrow by vehicle compatibility, then compare the compatible designs.

If one assembly was damaged and you're replacing it with an exact match, you may only need that side.

If you're changing to a different aftermarket style, buying a matched driver-and-passenger set generally makes more sense so both sides use the same design and lighting configuration. OmniGarage distinguishes Driver, Passenger, Driver or Passenger, and Driver & Passenger products, so check the position before ordering.

Not always. Check the exact product.

A complete assembly may include the housing and lighting elements but still require existing bulbs, a wiring adapter, converter, driver, or other vehicle-specific component.

Factory lighting matters here. Some aftermarket headlights require additional converters specifically because the vehicle came with factory LEDs.

Before ordering, check what's included and what must be reused or purchased separately.

Possibly. This is especially important on vehicles offered with multiple factory lighting systems.

For example, some AlphaRex headlights fit a particular truck but require one converter for the factory LED-reflector version and a different converter for the factory LED-projector version.

Don't assume the connector is correct just because the assembly physically fits the vehicle.
