What’s Included?

The package contains:

• Driver-side headlight assembly
• Passenger-side headlight assembly
• High beam bulbs
• Low beam bulbs

Turn signal bulbs are not included.

Having the primary bulbs included can simplify installation and eliminate the need to reuse older bulbs.

Why Replace Complete Headlight Assemblies?

Over time, factory headlights experience:

• Lens oxidation
• UV damage
• Moisture intrusion
• Cracked housings
• Faded reflector bowls
• Reduced beam output

Replacing the complete housing restores reflector efficiency and lens clarity that polishing alone cannot achieve.

Brighter Road Illumination

These headlights use high-transmittance polycarbonate lenses paired with high-reflectivity BMC reflectors.

Benefits include:

• Improved nighttime visibility
• Wider beam pattern
• Better shoulder illumination
• Enhanced visibility during rain and snow
• Increased driver confidence after dark

The fresh reflector surfaces help maximize the output of the included halogen bulbs.

UV-Coated Polycarbonate Lenses

Each lens features a UV-resistant protective coating designed to reduce long-term wear.

Advantages include:

• Resists yellowing
• Improved scratch resistance
• Better optical clarity
• Long-lasting transparency
• Enhanced appearance

This helps maintain consistent lighting performance over years of daily driving.

IP65 Waterproof Construction

Weather resistance is essential for trucks exposed to harsh environments.

The sealed housing provides:

• IP65-rated water resistance
• Moisture protection
• Reduced condensation
• Dust resistance
• Reliable year-round performance

Proper sealing helps protect internal reflectors and electrical components.

Plug-and-Play Installation

These assemblies are engineered to match factory mounting locations.

Installation features include:

• Direct bolt-on replacement
• Factory-style connectors
• No cutting
• No drilling
• No wiring modifications

Most DIY installers can complete the installation with basic hand tools.

OEM Replacement vs Restoring Old Headlights

If your housings contain moisture or the reflector surfaces are deteriorated, replacement is generally the better long-term solution.

Who Should Buy These Headlights?

These assemblies are ideal for:

• Daily drivers
• Fleet trucks
• Tow vehicles
• Work trucks
• Restoration projects
• High-mileage GMT800 owners

They are especially well-suited for owners seeking OEM-style performance without moving to aftermarket projector or LED systems.
