Nilight Fog Light Assembly for 2003-2006 GMC Sierra 1500 — Pair with H10 3300K Bulbs, OE Fit & DOT Compliant

Nilight fog light assembly designed as a direct, DOT-compliant replacement for 2003–2006 GMC Sierra 1500 models—sold as a pair with H10 bulbs for easy bolt-on installation.

Upgrade or replace damaged factory fog lights with this Nilight assembly engineered to match OE fit and function for 2003–2006 GMC Sierra 1500, 1500 HD, 2500, 2500 HD, 3500 and the 2007 Sierra Classic model. These assemblies are not compatible with Denali or C3 models; confirm vehicle fitment before purchase. Built with a high-transmittance glass lens, sealed housing, and DOT/SAE compliance, the lights restore visibility in poor weather while preserving the truck’s factory appearance.

How will these fog lights improve visibility in adverse weather?

Nilight fog lights use a 3300K clear lamp output that penetrates rain, fog, snow and dust more effectively than higher-color-temperature bulbs. The warmer, penetrating light reduces glare reflected back toward the driver and improves contrast on the road surface.

• 3300K light color for better penetration in fog and precipitation
• Included H10 bulbs matched to lens optics for optimized beam pattern
• Glass lens with high transmittance for maximum usable light
• Helps oncoming drivers notice your vehicle in low-visibility conditions

Will these fog lights fit my GMC Sierra without modifications?

Yes—this Nilight assembly is intended as a direct bolt-on replacement for the listed model years and trims, using the same mounting points and electrical connector types. No cutting or custom wiring is required when installing on compatible models.

• Replaces OE part numbers 15190984, 15190985, 15776382, 15776381
• Direct bolt-on installation; uses factory mounting locations
• Includes both driver and passenger side fog lights plus H10 bulbs
• Confirm compatibility: not suitable for Denali or C3 variants

How durable are these fog lights for everyday and off-road use?

The assemblies feature OEM-grade housings and a well-sealed design to keep out moisture and dust, giving reliable operation across different climates and terrains. The glass lens resists UV and heat, preserving clarity and light output over time.

• Sealed housing prevents water and dust ingress
• Impact-resistant construction built to withstand road debris
• UV- and heat-resistant glass for long-term clarity
• OEM-grade materials designed for factory-equivalent durability

What comes in the box and do I need professional help to install them?

The package includes a complete pair of fog light assemblies (driver and passenger) and a matched set of H10 bulbs. While these are designed for a straightforward bolt-on swap, professional installation is recommended if you’re unfamiliar with vehicle lighting or headlamp alignment.

• Pair of Nilight fog light assemblies (left and right)
• H10 bulbs included and pre-fitted for correct beam performance
• No additional brackets or major modifications required for compatible trucks
• Professional installation advised for proper alignment and wiring checks
