Abstract
An underwater light system includes a waterproof housing for enclosing a light source. According to one embodiment the housing has a removable, transparent, acrylic dome which seats onto a metal base. Strobe light electric circuitry and one or more light bulbs or other light sources are disposed inside the housing. The housing is configured to be vacuum sealed, and the removable nature of the dome and metal base permits convenient access to the light sources for replacement or other maintenance. An external electrical cable provides power via an external power source for the light sources while in use underwater. The power source is disposed apart from the housing, and the external power cable remains attached to the housing while underwater and in use.
