LSM is a slidermounted lighting system designed to provide visual marking of parachutists and/or aerial loads for collision avoidance and tracking during training and tactical operations. The LSM is available in both visible and infrared versions. Improvements in the second generation include snagresistant features, enhanced battery security, and lower profile. The LSM system comprises two highintensity LED based luminaires, control circuitry, and a replaceable CR123 battery mounted within a lightweight nylon carrier. Automatic activation is achieved immediately upon deployment of the parachute canopy. The LSM provides two bright points of light for marking the parachutist or load plus low level illumination of the parachute canopy. LSM's are userspecified and designed for specific rigs and sliders. Installation and Rigging: The LSM can be sewn directly onto the leading edge of the slider or set up for VelcroTM mounting to provide quick replacement or changeout from training to operational use. Devices are provided with rigging and maintenance instructions. Testing: The LSM, both sewn on and Velcro attached versions have been jump tested and verified by the military and parachute manufacturers under both day and night conditions.
