Overview: This is a 4" Ultra-Slim LED Light Bar Kit. Pro-Line is proud to introduce our next generation of LED lightbars for your RC vehicles! 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. A universal mounting kit is included with every light bar, with 3 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. All hardware is included for your convenience. The Ultra-Slim light bars are available in 4 different sizes to suit a huge variety of vehicles. The 2" bar is perfect for grille or bumper mounting on your 1/10 rig but also works great on the roof of an SCX24 body. Choose a 4" Straight, 5" Curved, or 6" Curved for your 1/10, 1/8, or even 1/6 scale crawlers, monster trucks, or whatever else you can dream up
