ABSTRACT:
A multi-function lighting device includes a barrel, a lamp mounted on one end of the barrel, a tubular coupling member secured around one end of the barrel, a tubular sleeve member made of a light transmittable material and sleeved slidably on the coupling member, and a head cap secured to one end of the sleeve member and provided with a reflector therein. The sleeve member is shiftable with respect to the coupling member between a first position, wherein the lamp extends into the reflector so that light may be directed axially, and a second position, wherein the lamp is located in the sleeve member so that light can pass transversely through the sleeve member. The barrel houses a battery therein, and a switch assembly is mounted in the barrel and is connected electrically to the battery and the lamp. The switch assembly is operable so as to interconnect electrically and selectively the battery and the lamp and so as to cause the lamp to generate one of a constant light output and a blinking light output.
