"The Vision X 7" round headlight will replace the factory JK Wrangler headlight. Installation is easy because its plug and play and everything is included. The Vision X LED lights are DOT approved, and feature super bright LEDs for illumination as well as a halo style accent ring around the light to be used as auxiliary lighting or wired in as a Daytime Running Light. These LED lights have a ice-phobic coating that prevents ice and snow from building up on the LED at colder temperatures. Lastly Vision X added light to fill in the dead zone directly in front of your Jeep. With other LEDs you may find that you have an area directly in front of the Jeep (5 feet or so) that isn't filled with light, Vision X has addressed this and will fill the area with light."
