The Sylvania ZevoPulse and Hybrid are designed to add color and an interactive experience to headlight assemblies through Bluetooth technology. With Zevo Pulse, users can add color to headlight assemblies that can be pulsed to music using the free Zevo smart phone app. The app can control multiple Zevo products within a vehicle. Zevo Pulse is a coin-sized chrome-finished LED disk that mounts to the outside of the headlight assembly and blends in with most vehicles. The Zevo Hybrid is similar, but with a more discreet application. The LED that delivers the colored light snaps onto the 9005 high beam, 9006 low beam and 9145 fog lights.
