OverviewIntroducing Form Lighting amber DRL LED headlights compatible with GMC Sierra 2014-2019! Like our popular white DRL option these lights use three bi-LED projectors to produce higher intensity and output of high and low beams.Modern Styling. These new blacked-out headlamps include smoked turn signals amber DRL and sidemarker lenses. 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 slow and smooth chasing pattern from the top of the lamp to the bottom and then fully illuminate 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.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.Road Legal.
