Description
Product Overview. The Diode Dynamics HD Headlight LED Halo Rings; Switchback are high-performance lighting upgrades designed to enhance your vehicle’s aesthetics and functionality. These halos emit a bright, uniform glow with switchback capability for daytime running lights and turn signals, providing both style and safety. They integrate seamlessly with factory wiring without requiring external controllers, delivering an OEM-like operation.
Construction and Appearance. Constructed with a proprietary phosphor coating and diffusing gel, these halos provide smooth, consistent light output with concealed LEDs when off for a clean look. Featuring high-density LEDs for maximum brightness, the components are assembled in the USA and include durable braided wiring along with waterproof drivers to ensure longevity and reliability.
Installation. Installation involves opening and resealing the headlamp housing and mounting the halos using integrated tabs with adhesive or beading wire. The procedure is moderately involved and typically takes 1-2 hours, with no drilling required.
Warranty. This product is backed by a 3-year limited replacement warranty.
Application. Specifically designed for the 2015 to 2021 Subaru WRX Base and Premium trims, these halos are not compatible with the Limited trim due to differences in headlight housing dimensions and design.
