The Baton Grip Light is an attachment for expandable police batons including ASP and Monadnock with an approximate diameter of 1 inch. The unique patented design provides increased weapon retention and an immediately accessible squeeze activated LED light with a 12+ hour burn time. Unlike other light attachments for expandable batons, the Baton Grip Light does not add any length to the baton, and is compatible with most baton carriers on the market. The Photon Micro Light can be easily removed for battery replacement. Additional lights available in several colors and styles including the Photon Micro Light II with on/off switch and squeeze function. Includes two CR-2016 lithium batteries. EXPANDABLE BATON NOT INCLUDED.
