Description

The Diode Dynamics HD LED Halos are designed for the 2016-2018 GMC Sierra 1500. They provide a brighter, more uniform appearance compared to the factory C-shaped DRL. These computer-designed LED circuit boards align perfectly behind the factory diffusing reflector and are available in switchback functionality.

The application-specific halos illuminate with higher intensity due to proprietary high-density HDLED technology, populated with over 700 LED chips and coated with a diffusing gel for a uniform light. The halos are powered by custom-designed drivers with advanced features like transient voltage suppression and multi-stage PWM dimming for adjustable brightness.
