Full LED Reflector Performance

Replace outdated factory halogen headlights with Form Lighting's advanced full LED reflector technology engineered for superior illumination. Application-specific optical reflectors provide a brighter, wider, and more uniform beam pattern for enhanced nighttime visibility while maintaining excellent light distribution for everyday driving.

Modern GMC Sierra Styling

Inspired by the latest Sierra models, these headlights instantly refresh your truck’s appearance with sleek, factory-inspired styling. The signature C-shaped LED daytime running light and integrated LED turn signals create a clean, premium look that complements both stock and lifted trucks.

Dynamic Startup Sequence

Every time your running lights activate, these headlights perform an impressive two-stage LED welcome sequence, illuminating the DRLs with a smooth chasing animation for a refined OEM+ appearance that stands out day and night.

Sequential LED Turn Signals

Complete the modern lighting package with integrated sequential amber LED turn signals. Instead of a standard flashing indicator, the LEDs illuminate in a smooth sweeping pattern, increasing visibility while adding a distinctive premium touch.

OEM-Grade Construction

Built to meet the highest quality standards, Form Lighting headlights feature premium automotive components for dependable long-term performance, including:

• Full LED low and high beam reflector optics
• UV-coated polycarbonate lenses for maximum clarity
• Automotive-grade LED emitters
• OEM-style plug-and-play connectors
• Integrated breather vents to reduce condensation
• Manufactured in an IATF 16949-certified automotive facility

The result is a durable, factory-quality headlight designed to withstand years of daily driving.

True Plug-and-Play Installation

These headlights are engineered as a direct bolt-on replacement for your factory assemblies. They install using the original mounting locations and factory connectors with no cutting, splicing, flickering, or hyperflash. A supplied DRL harness makes it easy to enable the daytime running lights on trucks not originally equipped with factory DRLs.

DOT & SAE Compliant

Form Lighting LED reflector headlights meet SAE, DOT, FMVSS, and CMVSS standards for legal on-road use in the United States and Canada when properly installed and aimed using the integrated adjustment screws.
