WEELMOTO Headlight Assemblies for 1999–2006 GMC Sierra & Yukon — Chrome Bezels, DOT-Compliant Optics

If your Sierra or Yukon needs headlights that match factory dimensions while improving durability and beam quality, these WEELMOTO assemblies are built as a direct replacement for a wide range of late‑90s and early‑2000s GMC models. They come with chrome bezels, DOT and SAE-tested optics, and are produced under an ISO/IATF quality system. Bulbs are not included, so the assemblies are ready to accept your vehicle’s stock lamps for a true plug‑and‑play swap.

Will these headlights fit my specific GMC model and year?

They suit DIY installers and professional shops that need a reliable, DOT-compliant assembly for restoration, accident repair, or upgrading aged housings—provided you supply the bulbs. If you drive a model listed in the compatibility notes and need dependable fitment backed by quality testing and a multi-year support policy, these assemblies are a practical upgrade.
