The present invention provides a novel waterproof head assembly specifically designed for LED sources. The rounded end surfaces of the LED are exposed to the outside environment through apertures formed in a solid end wall of the head assembly. To prevent water from entering into the interior of the flashlight through the apertures, the present invention discloses filling the interior cavity of the head with a sealant which substantially entirely fills all of the gaps between the outside surfaces of the LED's, the inside surfaces of the apertures, and the inside surfaces of the open end of the head assembly.
