Abstract
A flashlight having a flashlight head with two merged yet independent lamp/reflector systems, the head including a common reflector structure having two reflectors of differing light projecting characteristics, the two reflectors arranged side by side with a common boundary across part of the common reflector structure. A flashlight holder and battery charger includes interacting surfaces on the flashlight and the holder that permit insertion of the flashlight into the holder only when the flashlight is in a predetermined position relative to the holder, require that the flashlight be manually moved or rotated in a predetermined direction after insertion for locking the flashlight in the holder and for permitting battery charging only when the flashlight's lamps are disconnected from the batteries, and require that the flashlight be manually moved or rotated in the opposite direction for permitting removal of the flashlight from the holder. A sequential switching arrangement on the flashlight changes the light output of the dual lamp flashlight according to the distance by which a push-button on the flashlight is depressed.
