Form Lighting Triple Bi-LED Projector Headlights – 2014-2019 GMC Sierra | Sequential Turn Signal | C-Shaped DRL

Form Lighting's LED Projector Headlights for the 2014–2019 GMC Sierra are a premium OE-grade headlight replacement that transforms the Sierra's lighting output and visual presence in a single bolt-on upgrade. Built around three bi-LED projector units per headlight — each providing both low beam and high beam output — these headlights deliver dramatically improved illumination intensity, beam pattern precision, and light output over the factory halogen units. Inspired by the modern Sierra's styling direction, the Form Lighting headlights bring a distinctive C-shaped LED DRL signature, sequential amber turn signals, and a two-stage startup sequence to the 2014–2019 Sierra — a modern lighting package that updates the truck's appearance and capability in one installation. Fully plug-and-play with no wiring modifications required, SAE/DOT/FMVSS/CMVSS compliant for legal on-road use in the US and Canada.

Key Features:

• Triple bi-LED projectors — three bi-LED projector units per headlight, each providing both low beam and high beam output — delivering a sharp cutoff, broad beam width, and high-intensity illumination that significantly outperforms the factory halogen projector
• C-shaped LED DRL — distinctive C-shaped daytime running light signature inspired by the modern Sierra's styling direction — a clean, premium DRL design that updates the 2014–2019 Sierra's appearance
• Sequential LED turn signal — sequential (sweeping) amber LED turn signal animation for a distinctive, high-visibility turn indication that stands out from factory and aftermarket alternatives
• Startup / welcome sequence — when the running lights activate, the DRL illuminates in a two-stage chasing sequence for a premium, modern lighting signature
• OE-grade construction — UV-coated polycarbonate lenses, automotive-grade LEDs, and OEM connectors throughout — built to OE material and durability standards
• SAE / DOT / FMVSS / CMVSS compliant — meets all applicable US and Canadian on-road lighting standards when installed and aimed correctly — road legal in the United States and Canada
• Plug-and-play installation — designed to plug directly into the factory Sierra headlight connector with no wiring modifications — no errors, flickering, or hyperflashing
• DRL fusebox harness included — fusebox wire harness included to enable the DRL feature on Sierra trucks not equipped with factory daytime running lights

Performance & Feature Benefits:

• Triple Bi-LED Projector Output: Three bi-LED projectors per headlight — versus the single projector in the factory Sierra headlight — deliver a fundamentally different level of illumination. Each projector produces a sharp, precise cutoff beam pattern that maximizes road illumination while minimizing glare for oncoming traffic. The combined output of three bi-LED units provides broad beam width, high intensity, and consistent colour temperature that halogen projectors cannot match — a meaningful safety and visibility upgrade for night driving and adverse weather conditions
• C-Shaped DRL Signature: The distinctive C-shaped LED DRL is inspired by the modern GMC Sierra's styling direction — bringing a contemporary, premium DRL aesthetic to the 2014–2019 Sierra that bridges the gap between the truck's generation and current GMC design language. The C-DRL is immediately recognizable and significantly more visually distinctive than the factory DRL or basic aftermarket LED strip alternatives
• Sequential Turn Signal: Sequential LED turn signals sweep from inboard to outboard in a smooth, progressive amber animation — providing a highly visible, distinctive turn indication that is immediately recognizable and significantly more attention-grabbing than a standard static turn signal. Sequential turn signals are a hallmark of premium and performance vehicle lighting design
• Startup Sequence: The two-stage chasing startup sequence activates every time the running lights turn on — a premium lighting signature that distinguishes the Sierra from factory and basic aftermarket headlight alternatives
• OE-Grade Materials: UV-coated polycarbonate lenses resist yellowing and hazing over time — maintaining optical clarity and appearance across the full service life of the headlight. Automotive-grade LEDs and OEM connectors ensure long-term reliability and correct electrical compatibility with the Sierra's factory lighting control system
• Road Legal Compliance: SAE, DOT, FMVSS, and CMVSS compliance confirms that the Form Lighting headlights meet all applicable US and Canadian on-road lighting standards — providing confidence in the headlights' legal status for street use when installed and aimed correctly
• Plug-and-Play Reliability: Direct plug-in compatibility with the factory Sierra headlight connector eliminates the wiring complexity and error codes that affect many aftermarket headlight upgrades. No resistors, decoders, or wiring modifications required

Why Upgrade the Sierra's Headlights?

The factory 2014–2019 GMC Sierra headlight is a capable unit for a stock truck — but its single halogen projector and basic DRL design leave significant room for improvement in both lighting output and visual presence. For Sierra owners who drive at night, tow, or haul in low-light conditions, or who simply want a lighting upgrade that matches the quality and modernity of the rest of their build, Form Lighting's triple bi-LED projector headlights represent a transformative upgrade. Three bi-LED projectors per side deliver a level of illumination that the factory halogen unit cannot approach — while the C-shaped DRL, sequential turn signal, and startup sequence bring a level of lighting sophistication that rivals premium factory lighting systems costing far more.

Why Form Lighting?

Form Lighting is a specialist aftermarket LED lighting brand focused on delivering OE-grade fit, finish, and plug-and-play electrical compatibility — with a product lineup developed specifically for popular truck and SUV platforms where the factory lighting is a known limitation. Form Lighting's engineering emphasis on plug-and-play compatibility, precise fitment, road-legal compliance, and OE-grade materials addresses the most common pain points of aftermarket headlight upgrades — delivering a headlight that installs cleanly, operates reliably, and looks premium from day one. For Sierra owners who want a headlight upgrade that performs as well as it looks, Form Lighting is the correct choice.

Perfect For:

• 2014–2019 GMC Sierra owners seeking a significant improvement in nighttime illumination and beam pattern quality over the factory halogen headlights
• Sierra builds where a modern, premium lighting signature — C-shaped DRL, sequential turn signals, startup sequence — is a priority
• Towing and hauling applications where improved forward illumination is a safety requirement for night driving
• Owners who want a clean, road-legal OEM-plus headlight upgrade without the complexity of custom wiring or error code management

Pro Tip: After installation, have your headlights professionally aimed to ensure the triple bi-LED projector beam pattern is correctly aligned for maximum road illumination and minimum glare for oncoming traffic. Most alignment shops can aim aftermarket projector headlights in under 30 minutes — a small investment that ensures you get the full benefit of the Form Lighting headlights' output.
