This seems perfect for boats that don't have a built-in electrical system to light cuddy cabins, or dark lockers. A peel-off velcro strip is included but batteries are not. Here is the manufacturer's description:

Instrument Panels, Cockpit Areas, Walkways, Bathroom Heads, Rod Lockers, Closets, Storage Compartments, Rod Lockers, Under Cabinets, Bimini Light, Reading Light, Walking, Biking, Hiking, Car/Truck Visor Light, Tent Light, Child Light, and many more applications.
