GMC Sierra LED Halos Switchback 16-18 Sierra 1500 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. Pure white color. Manufactured in USA, the modules light in a pure 6000K white color, not a cool blue like cheaper products on the market. And because they use modern high-power amber chips, rather than traditional LEDs, the amber is even brighter than the white!Constant-current power. To power the modules efficiently, your order includes two custom-designed drivers, which feature transient voltage suppression, reverse protection, and a switching driver for extremely high reliability over time. And here's what really makes this product shine over the competition: with an embedded microcontroller, the drivers utilize multi-stage PWM dimming, to allow for a half-brightness white, for use at night (parking lights), as well as a full-power white, for use as DRL during the day. Finally, the amber is run at even higher power, making the turn signal easily visible in broad daylight! Professional installation is strongly recommended, as the factory headlights must be opened for installation. The halos must be custom-mounted in position using adhesive or beading wire. Experience. After over a decade in business, Diode Dynamics is the most trusted name in automotive LED lighting.
