Let there be light
Easy to mount and wire. Seems to be made sturdy for trail riding. Easy to see behind utv on dusty trails.

Work great
Just to let people know, they dont work very well unless there is something in the air to reflect the light off like sand, rain or fog. I like them for trail riding in the dunes. More noticable than just a normal lighted whip.
