Upgrade your GMC Sierra with full LED performance and modern styling using Form Lighting LED Reflector Headlights by Form Lighting. Featuring application-specific reflector optics, sequential LED turn signals, and a distinctive C-shaped DRL, these headlights transform both the appearance and nighttime visibility of your truck.
Full LED Performance for the GMC Sierra
While many Sierra models include partial LED lighting from the factory, they still rely on halogen components for key functions. These LED reflector headlights upgrade the system to full LED output, providing stronger light intensity and improved road illumination.
Using custom-designed reflector optics and automotive-grade LED emitters, the beam pattern delivers excellent brightness and distribution while maintaining safe road compliance.
Modern Sierra-Inspired Styling
These headlights are designed to complement late-model GMC Sierra styling with a more aggressive front-end appearance.
C-Shaped Daytime Running Light
A bold C-shaped LED DRL creates a distinctive signature that matches modern Sierra design language.
If your truck did not originally include daytime running lights, the included DRL harness allows easy activation.
Sequential LED Turn Signals
Integrated amber turn signals illuminate in a smooth sequential pattern, improving signaling visibility while adding a modern aesthetic.
Startup Welcome Sequence
Every time the running lights activate, the headlights perform a two-stage animated startup sequence, creating a premium look that sets your truck apart.
