The ModButton Lite from Modlite Systems® is a small remote activation switch with big features. Like its big brother, the ModButton, the ModButton Lite features the same improved electronics to fire high output weapon lights at full power. Built into an impact-resistant polymer housing, the ModButton Lite clamps onto in-spec M1913 Picatinny rails for a solid and consistent switch placement. An adapter for MLOK rails is sold separately.
This variant will work with Surefire® tail caps such as the UE and DS00.
Note on cable length options: For almost all use cases the 4.5″ variant is what you want to buy. Unless you have a special setup the 4.5″ cable is going to be plenty even running a laser.
