Cyclops Micro Mini LED Hat Clip Light. Features 5 white LED bulbs with a built-in 15 degree angle tilt. Black housing. Top mount design does not obstruct line of vision. Sturdy metal clip. Weighs less than an ounce. Uses two CR2016 batteries (included). I've personally used a Cyclops cap light for a long time and have never been dissapointed in the design and service it provides. The Micro Mini is so light you won't notice it on the bill of your cap. It is bright enough to be useable, but not so bright it will blind your night vision. Unbelievably handy when working with your hands in the dark. Imported.
