Crimson Trace have launched a laser and light grip for AR-15 / picatinny rail’d rifles.

From Crimson Trace:

White light equipment for AR-15 and other picatinny rail-equipped rifles has for years involved clamping a rather large flashlight to the rails, and attaching an activation pad to the foregrip via an external wire. Enter the MVF-515 Modular Vertical Foregrip, with its compact and rugged design and our total instinctive activation system which allows the shooter to activate all combinations of light & laser, instinctively, while maintaining their natural shooting grip. And there are no external wires or loosely attached activation pads
