Insight Technology VLI (Visible Light Illuminator) was the selected weapon light system in the original SOPMOD M4 accessory kit. It was issued to the USSOCOM communities in the late 1990s and early 2000s.
VLI is an extremely powerful visible illuminator that emits a highly concentrated beam of visible light for acquisition and identification. It is powered by either 3 CR-123A batteries or by 6 AA batteries. VLI can be used with Night Vision Devices and can be used as either a handheld illuminator or can be weapon mounted using the VLI’s Integral Rail Grabber Mounting Bracket. The bracket fits the KAC Rail Interface System (RIS) which provides MIL-STD-1913 mounting rails. In weapon mounted mode, the VLI can be used to accurately direct fire as well as illuminate and designate targets. VLI also comes with two filters (infrared and red) and a cable switch that provides fingertip control of the VLI using a rubber membrane style switch.
