LED lighting and modern styling
Form Lighting 2015-2019 GMC Sierra 2500/3500 LED Projector Headlights With Amber DRL with integrated LED lighting and modern replacement-housing styling.
Retain the model-specific lighting functions described below, with OEM-grade materials and factory mounting compatibility.
Introducing Form Lighting GMC Sierra headlights with an amber DRL! Like Form Lighting's popular white DRL option, these lights upgrade your headlights to full LED, along with a number of other modern features.
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.
Modern Styling. Inspired by the late-model Sierra styling, these lights will give your truck a much more modern appearance. These new blacked-out headlamps include smoked lenses for the turn signal, amber DRL, and sidemarker. If your factory headlights don’t have a DRL, no worries! Installation of this feature is simple thanks to the included harness.
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 amber in a smooth chasing pattern from the top of the lamp to the bottom, before fully illuminating in a brilliant amber that is sure to turn heads.
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 in a smooth chasing sequence, with an ultra-premium look.
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. The low beam and high beam on these Form Lighting headlights meet DOT standards 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.
