Nilight Headlight & Taillight Assembly Combo for 2003-2006 Chevy Silverado Fleetside — Sealed DOT/SAE Pair

Nilight's headlight and taillight assembly combo replaces both front and rear lamps on compatible Chevy Silverado Fleetside trucks, restoring factory-style illumination and appearance.

These complete lamp assemblies are built for Silverado models from the mid-2000s and combine rugged construction with straightforward installation. Designed as direct-fit replacements for Fleetside (not Barn Door or Stepside) variants, the set comes with driver- and passenger-side taillights and headlight housings — taillight bulbs are included while headlight bulbs are not. Every unit is sealed against the elements and meets DOT/SAE requirements for street use.

Will these fit my 2003–2006 Chevy Silverado?

The assemblies fit 2003–2006 Chevy Silverado 1500/1500HD/2500/2500HD and 2004–2006 3500 models, plus the 2007 Classic 1500/2500/3500, only for Fleetside bed styles. They will not fit Barn Door or Stepside trucks, so verify body style before ordering.

• Compatible with: 2003–2006 Silverado 1500, 1500HD, 2500, 2500HD.
• Also fits: 2004–2006 Silverado 3500 and 2007 Silverado Classic series.
• Does not fit: Barn Door or Stepside bed models.
• Tip: Check your VIN or current lamp shape to confirm Fleetside fitment.

How durable are these assemblies in bad weather?

Nilight housings are designed to resist impact, vibration and common environmental damage. Each assembly is fully sealed with silicone to keep out moisture and contaminants, which helps prevent fogging, corrosion and premature deterioration in rain, snow or dusty conditions.

• High-impact housing resists shocks and road vibration.
• Fully sealed silicone gasket prevents water intrusion and fogging.
• Corrosion-resistant finishes extend service life in harsh climates.

Do these meet safety and legal standards for road use?

Yes — the headlight and taillight assemblies are manufactured to meet DOT and SAE specifications, ensuring they comply with common regulatory requirements for on-road lighting. Upgrading to these assemblies improves visibility to other drivers while preserving lawful operation when installed correctly.

• DOT & SAE compliant for street-legal use.
• Designed to provide clear, recognizable signaling for other road users.
• Proper alignment and bulb selection remain important for correct beam pattern.

Is installation difficult and what is included in the package?

Installation is intended to be plug-and-play using OE-style sockets, so no drilling or body modification is required for a direct swap. The package contains one pair of headlights and one pair of taillights (driver and passenger sides); taillight bulbs are included but headlight bulbs are not, and professional installation is recommended if you are not comfortable with vehicle electricals.

• Plug-and-play replacement using original-style connectors.
• Package: one pair headlights and one pair taillights (driver & passenger).
• Taillight bulbs included; headlight bulbs must be purchased separately.
• Professional installation advised for best alignment and wiring safety.

Who is this for: This full headlight and taillight set is aimed at owners of mid-2000s Chevy Silverado Fleetside trucks who want to restore factory appearance, improve rear and front lamp functionality, or replace weather-damaged housings with DOT-compliant assemblies. It’s a practical choice for DIYers familiar with basic automotive wiring and bolt-on replacements, and for service shops installing direct-fit lighting components on compatible Silverado models.
