Inter-American Security Products, Inc. has litton night vision equipment, like scopes, binoculars and goggles. The single tube litton night vision goggle is intended for land use including vehicle driving. The night vision apparatus is worn on a head mount or helmet mount device. When using the optional helmet mount, it will automatically shut off in the up position. The night vision goggle and its adaptor are independently removable from the helmet strap. The litton night vision apparatus has an exterior infrared light source to illuminate the nearby scene so that the user may read maps, do night-time repair or maintenance work, or tend to injured military personnel.
