These kits are for Tactical operations (indoor flying) where light is needed for interior illumination as well as allowing light for the positioning sensor to maintain steady flight. 4 Light system with two front Lights, and two bottom lights, and now a snap in battery holder to ensure battery does not eject on crash. We also have an option for the front metal gimbal guards (seen in red) and rear bumpers for extra protection if needed. (see drop down for adding options they are not included on the basic tactical kit.) Designed for public safety tactical missions!
