This light is the cats meow! I mounted it on the dash of my KLR and use it all the time on night rides. Rotates 360o and tilts 45o. Has a magnetic base and a stick-on Velcro stick pad so you can pull it off and look in your tank bag, luggage or check maps. About 2” diameter with 100,000 hour battery. A bright and handy little light for very little money.
