WEELMOTO Halogen Headlight Assemblies for 1999–2006 GMC Sierra & Yukon — Direct-Fit, DOT-Compliant

WEELMOTO halogen headlight assemblies are direct-fit replacements for many 1999–2006 GMC Sierra and Yukon models, matching OEM fit and light pattern for reliable night driving.

These plug-and-play halogen headlight assemblies are engineered to replace worn or damaged headlights on select GMC Sierra and Yukon trucks and SUVs. Built to meet DOT standards and manufactured under an IATF16949-certified process, they combine chrome-plated bezels, durable materials, and a tested optical pattern to restore original-style illumination without modifying your vehicle.

Which GMC models and years will these headlights fit?

These assemblies are designed to match OEM numbers 15850351 and 15850352 and fit a wide range of Sierra and Yukon models. They are tailored for 1999–2006 Sierra 1500, many 2001–2006 Sierra 2500/3500/1500 HD variants, 1999–2006 Yukon and 2000–2006 Yukon XL, plus several Classic and C3 listings. Note they do not fit some Denali trims or the 1999 Sierra Old Body Style.

How durable and weather-resistant are these replacement headlights?

WEELMOTO assemblies undergo multiple environmental and mechanical tests, including drop, vibration, rain, UV exposure, sand, and dust spray. The materials and chrome bezel plating are selected for corrosion resistance and long-term stability, so the assemblies keep their look and function through typical road conditions.

• Tested for vibration, impact, UV and water intrusion
• Durable chrome-plated bezel for corrosion resistance
• Sealed housings reduce moisture and dust entry
• Designed for extended lifespan under normal driving

What kind of light performance should I expect after installation?

The assemblies are engineered with a verified light pattern that follows SAE guidelines to deliver broad and predictable halogen illumination. While they accept your vehicle's original halogen bulbs, the reflector and lens geometry is optimized to provide consistent beam cutoff and road coverage similar to factory output.

• SAE-compliant light pattern for uniform beam spread
• Chrome reflector and lens designed for efficient halogen output
• Maintains factory-style cutoff and road illumination
• Best used with stock halogen bulbs (not included)

Is installation straightforward and what support is available?

Installation is intended to be plug-and-play using the existing vehicle harness and mounting points; no cutting or special adapters typically required. WEELMOTO provides an installation manual and offers a 1-to-1 customer service line plus a 3-year assurance period for manufacturing concerns.

• Plug-and-play design matches factory connectors and mounts
• Installation manual included with each kit
• 1-to-1 customer support through WEELMOTO for fitment questions
• 3-year limited assurance against manufacturing defects

Who is this for: These headlight assemblies are ideal for GMC owners who need a direct replacement that restores factory fit, finish, and beam pattern without aftermarket rewiring. Choose these if you own a compatible 1999–2006 Sierra or Yukon model, want DOT-compliant components produced to automotive quality standards, and prefer a straightforward installation using your vehicle’s existing halogen bulbs.
