The Nitro 360™ Fog Light Kit offers the ability to adjust to any driving conditions by simply using the vehicle's fog light switch the LED will change from a 6,000K Ultra White to a 3,000K Crisp Yellow LED output color. The yellow fog light is proven to perform better in conditions such as rain, snow, and fog. White performs better for max visibility in clear conditions.

In addition to these features, the Nitro 360 includes a 360° light pattern on the bulb itself to make full use of the fog light housing and optimize light output points for improved peripheral visibility. 100% Plug&play with no extra switches or wiring needed.
