GMC Sierra LED Halos Switchback 16-18 Sierra 1500 Diode Dynamics

Time for an upgrade! From the factory, the Sierra comes with a white C-shaped DRL that from certain angles can look segmented and distorted. Diode Dynamics is excited to release our HD LED Halos for the 2016-2018 GMC Sierra that provides a much brighter, more uniform appearance compared to the factory optics. These computer-designed LED Halos are circuit boards that align perfectly behind the factory diffusing reflector. Available in switchback and amber-only, both versions also function as an additional front turn signal for a custom, yet functional look! High output, clean appearance. The custom-designed LED modules replace the factory bulb or single LED, illuminating with a much higher intensity. With our proprietary high-density HDLED technology, these modules are populated with over 500 LED chips, which are then coated by a diffusing gel, resulting in a perfectly uniform light when turned on. When it's off, the diffusing gel hides the chips, resulting in a clean, OEM appearance. P
