Form Lighting LED Projector Headlights give the 2014-2018 GMC Sierra a serious upgrade in output, styling, and modern lighting function. This amber DRL version combines triple Bi-LED projector performance with a bold amber running light, blacked-out headlamp styling, and sequential LED turn signals.
The design is inspired by late-model Sierra styling, giving your truck a cleaner, more modern front end while keeping installation vehicle-specific and straightforward.
Key Features & Benefits
Triple Bi-LED Projector Output
These headlights use three Bi-LED projectors per side for both low beam and high beam illumination.
Features include:
- Triple projector design
- All three projectors are Bi-LED units
- Low beam and high beam LED output
- Sharp cutoff
- Broad beam width
- High-intensity output
This is a full headlight assembly upgrade, not a bulb swap inside factory housings.
Amber Daytime Running Light
This version features a brilliant amber DRL for a bold front-end appearance.
Features include:
- Amber DRL design
- Smoked DRL lens
- Modern Sierra-inspired styling
- Included DRL harness
- No wire cutting or splicing listed for DRL activation
If your factory headlights do not have DRLs, the included fusebox harness allows the DRL feature to be added cleanly.
Startup Sequence
The amber DRL includes a welcome-style startup sequence when the running lights turn on.
Features include:
- Smooth amber chasing pattern
- Top-to-bottom illumination sequence
- Fully illuminates amber after startup
- Activates with running lights
- Premium modern lighting effect
This gives the truck a more custom, high-end appearance every time the running lights activate.
Sequential LED Turn Signal
The integrated sequential turn signal adds a modern signal function to the front end.
Features include:
- Amber LED turn signal
- Sequential chasing motion
- Integrated into the headlight assembly
- Smoked turn signal lens
- Premium lighting appearance
This adds a more distinctive look than a standard flashing turn signal.
Blacked-Out Modern Styling
The headlamp design gives the Sierra a sharper, updated front-end look.
Features include:
- Blacked-out headlamp appearance
- Smoked turn signal lens
- Smoked amber DRL lens
- Smoked sidemarker lens
- Late-model Sierra-inspired design
This is a strong option for Sierra owners who want a more aggressive front-end upgrade without using universal styling parts.
