Why Replace Your Factory Headlights?

Factory headlights fade, fog up, and dim over time. New aftermarket LED headlights last longer, shine brighter and give your truck a serious visibility boost—especially in poor weather or dark rural highways. Whether you want a factory match or a custom headlight housing with attitude, we’ve got what you need. Pair headlights with other products like clearance lights for commercial trucks or general truck lighting upgrades. Or beat pesky blindspots with a set of polished semi truck mirrors.

What Are the Main Types of Headlights?

When shopping for semi truck headlights, there are three primary types to know: - Halogen: Affordable and widely available. These use a tungsten filament and halogen gas to produce light. - HID (High-Intensity Discharge): Brighter than halogens with a bluish tint. They use gas rather than a filament and require ballasts. - LED (Light Emitting Diode): The most efficient and durable. LEDs offer a lot more brightness, consume less power, and last up to 20x longer than halogens.

Which is better—HID or Halogen?

HID lights are brighter and can last longer than halogens. LEDs are the industry standard, offering a longer lifespan, less heat, and more brightness.

What Does Adaptive Headlight Mean?

Adaptive headlights are a high-tech upgrade designed to move with your steering. As you turn, the beam follows the direction of the road—giving you better visibility around corners. Some advanced LED models also adjust brightness based on speed or surrounding light conditions.
