Overview With upgraded LED headlights compatible with GMC Sierra 2014-2019 from FORM Lighting, you can add full functionality to your truck, with a number of modern features. Using modern optical reflectors, these lights produce higher intensity and output of high and low beams. Modern Styling. Inspired by the latest model truck, these lights will give your ride a modern appearance. This includes an LED turn signal along with a distinctive C-shaped DRL. If your factory headlights don’t have DRL function, no worries! Installation is simple thanks to the included harness. Startup Sequence, Sequential Turn Signal. These headlights are packed with the latest modern lighting functions, including a startup or “welcome” sequence as well as sequential turn signal. Startup function includes the running lights illuminating in a two-stage chasing sequence. Similarly when the turn signal is activated, amber LEDs activate in a smooth, chasing sequence as well. OEM-Grade Construction. FORM Lighting headlights are built with quality in mind, using OE-grade materials. This includes UV-coated polycarbonate lenses, automotive-grade LEDs, and OEM connectors. While they may not be the cheapest option, 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. Plug-and-Play, Bolt-On Install. Our headlights are completely plug-and play and will fit perfectly, bolting right up to the factory mounting points without gaps. They were designed to plug into the factory headlight connectors, without modifications needed. No errors, flickering, or hyperflashing! To enable the DRL feature, a fusebox wire harness is included.
