The MaxMicro light is a size and shape designed specifically for use as a custom glove light in the tips of a glove. The body is shaped with a particular taper to resemble the dimensions of a fingertip for a comfortable fit inside a glove. The microlight is also a great shape to hold in your hand for play. This small microlight's body (not including the LED tip) measures 1" long, 3/4" wide, and 1/4" thick. The back slides out like a drawer and the batteries are easy to replace in seconds. The light is activated by pressing on the body once to turn on and again to turn off. The 7-color strobing LED creates awesome "dashed" rainbow light trails in motion. Comes with 2 diffuser tips (one open end, one closed end) that allow you to expand the thickness of the LED effect for fatter light trails. Uses 2 CR2016 batteries (included and replaceable).
