The Ultra-Slim lightbars feature a low-profile, highly detailed injection-molded housing that holds a super-bright strip of LEDs that run off 5-12V power. They come ready to use with plug & play industry-standard receiver plugs and a 12" lead that you can choose to plug directly into your receiver, or wire directly to a 2S or 3S battery. The lens on the lightbars has a dual focus combo, a spot pattern in the middle section and a diffused flood pattern towards the outer edges.The universal mounting kit is included with every light bar, with three different styles of mounts. The standard mounts and low-profile mounts allow you to fasten the lightbar to your roof or other body panels, while the tube clamp mounts allow for mounting to a cage or tube-style bumper! Plus, all the hardware needed is included for your convenience!
