I think ebay sells two or three light bar kits for the Teryx. I know I have seen them.
Actually the one I have is off Ebay. Please be careful of these. The mount is very weak and for some reason the light tabs are on the front rather than the top. This may sound minor but it completely takes out any ability to adjust the lights up and the angle is maxed out. This is the bar I'm junking if I can find a better one.
