Your 2015-2019 GMC Sierra deserves an upgrade and LED Headlights from Form Lighting are the perfect way to do it. With these premium OE-grade replacements, you’ll add triple bi-LED projectors, sequential turn signals, startup sequence, and a more aggressive, modern appearance.
Triple Projectors. What’s better than one projector? Three projectors. And in these headlights, all three are bi-LED units, providing output for both low beam and high beam illumination. With a sharp cutoff, broad width, and high intensity, these units provide a serious upgrade in output.
Startup Sequence. These headlights are packed with the latest and most modern lighting functions, including a startup or “welcome” sequence. Anytime the running lights turn on, they will illuminate in a two-stage chasing sequence that is sure to turn heads, with an ultra-premium look.
Sequential Turn Signal. The startup sequence isn’t the only thing that stands out. These headlights also feature an integrated sequential LED turn signal. Every time the turn signal is activated, amber LEDs activate across the bottom of the lamp in a smooth, chasing sequence. When you’re finished making your turn, they automatically “switch back” to the bright white DRL.
OEM-Grade Construction. Form Lighting headlights are built with quality in mind, using OE-grade materials and design techniques. This includes durable UV-coated polycarbonate lenses, automotive-grade LED emitters, breather vents, and OEM plug-and-play connectors. They are assembled in an IATF 16949-certified facility, which is a quality management system designed for the automotive industry. While they may not be the cheapest option you’ll find, you can rest assured that these lights will provide durable and superior performance.
Road Legal. Form Lighting headlights meet all SAE, DOT, FMVSS, and CMVSS standards and regulations for legal on-road use in the United States and Canada, when installed and aimed properly - which is easy to do with the integrated screw-type adjusters.
Plug-and-Play. Our headlights for the Sierra are completely plug-and play and will fit perfectly, without any gaps. They were designed to plug into your factory headlight connector, with no wiring modifications needed. No errors, flickering, or hyperflashing!
Two-Year Warranty. All Form Lighting products are rigorously tested for reliability, and backed by a two-year warranty. The warranty is supported directly by Form Lighting, and any replacement parts, if needed, are shipped quickly from Form Lighting’s US warehouse. In the rare occasion that you may need to utilize your warranty, we try to keep the process as simple as possible - for example, no return is normally necessary.
