WEELMOTO Headlights Assembly for 1999–2006 GMC Sierra & Yukon — Direct-Fit Chrome, DOT-Compliant

WEELMOTO Headlights Assembly is a direct-fit, DOT-compliant replacement set engineered to restore factory-style lighting and fit 1999–2006 GMC Sierra and compatible Yukon models without modification.

If your Sierra or Yukon headlights are cloudy, cracked, or failing, this WEELMOTO assembly is built as a plug-and-play swap to bring back correct alignment, reflector performance, and a polished chrome finish. These assemblies match OEM references (15850351, 15850352) and are designed to fit a broad range of GMC Sierra 1500/2500/3500 years and related Yukon variants — check compatibility carefully against your model year and trim before ordering.

Which GMC model years and trims will these WEELMOTO headlights fit?

These assemblies are manufactured to fit many Sierra and Yukon model years within the 1999–2007 range, but there are specific exclusions. They are a direct match for multiple Sierra 1500, 2500 HD, 3500 and Yukon configurations; however, not all Denali trims and certain 1999 old-body-style trucks are supported.

• Compatible with 1999–2006 GMC Sierra 1500 (select models) and 1999–2006 Yukon/Yukon XL
• Includes fitment for 2001–2006 Sierra 2500 HD/3500 and 2007 Sierra Classic models
• Not compatible with some Denali trims and 1999 Sierra old-body style
• Confirm OEM numbers 15850351 / 15850352 against your vehicle

How does installation work and are bulbs included?

Installation follows a plug-and-play approach using your truck’s existing mounting points and wiring harnesses, so professional tools are not usually required. Bulbs are not supplied with the assemblies, so you should reuse your stock bulbs or purchase replacements matched to your original equipment specifications.

• Comes with detailed installation instructions for a straightforward swap
• Uses factory connectors—no splicing or adapter needed in most cases
• Bulbs not included; use original bulbs or appropriate H-type replacements
• WEELMOTO offers 1-to-1 support and a 3-year reassurance period

What quality checks and performance standards do these headlights meet?

WEELMOTO designs these assemblies to comply with DOT visual and safety expectations and follows production controls under an IATF16949-informed quality system. Each unit undergoes durability testing to resist drops, vibration, moisture, UV exposure and dust so the assemblies retain fit and finish over time.

• DOT-compliant design and SAE-informed light pattern for reliable beam alignment
• Tested for drop, vibration, rain, UV, sand and dust resistance
• Chrome-plated bezel for lasting appearance and reflectivity
• Manufactured with high-durability materials to extend service life

What changes in light output or driving experience should I expect?

After installation you should regain predictable reflector behavior and beam cutoffs that match factory positioning, improving on old, dim, or hazed lenses. The chrome reflector and optical design are optimized to produce a clear beam pattern without scattering light, provided you use bulbs of appropriate wattage and type.

• Restores crisp beam pattern and alignment similar to original equipment
• Chrome bezel enhances brightness and optical efficiency
• Designed to meet SAE pattern guidance for road-legal output
• Performance depends on bulb type—use manufacturer-recommended bulbs

Who is this for? These WEELMOTO headlight assemblies are aimed at GMC owners who need a cost-effective, OEM-replacement solution to restore lighting performance and vehicle appearance. They suit DIYers who want a simple plug-and-play swap, fleet managers replacing multiple units to a consistent spec, and owners of older Sierra/Yukon models seeking DOT-compliant parts that replicate original fit and function. Always verify vehicle year, body style, and part numbers before purchase to ensure a correct match.
