one of the reasons was to blind people behind if they have their brights on, although I have to be at a stop lol. They also help 100% when backing up while using the reverse camera and backing into anything that will be on my hitch.Well one application I thought of was when someone behind you has their brights on it would be nice to flash them with this and singe their retinas a bit. Other than that, I am struggling with the why?![]()
