The TSM-12G Subcompact Tactical Weapon-Mounted Light with Green Laser for GLOCK pistols uses a super-bright LED rated at 150 lumens working in conjunction with a precision-engineered miniature reflector to create a bright white beam of light rated at 100 meters. This weapon light features completely ambidextrous and intuitive toggle switches on each side of the light to operate the momentary-on and constant-on lighting modes orClass IIIa 532nm daylight-visible green laser. These lighting modes include white light, laser, or both light and laser. The two glass-filled nylon plastic housings of the TSM-12G is designed to lock onto the front of the pistol's trigger guard for secure installation and the lowest profile possible.
