ABSTRACT:
A flashlight includes a barrel for receiving a battery unit therein, a bulb mounted in the barrel, a transparent housing threadedly engaged with a front end of the barrel, a reflective mirror mounted in the housing to move therewith, and a rear cap mounted to seal a rear end of the barrel. An outer casing is threadedly engaged around the housing such that rotational movement of the housing causes movements of the housing and the reflective mirror relative to the bulb to thereby place the bulb in a position either surrounded or not surrounded by the reflective mirror. A colored sleeve is removably mounted between the bulb and the housing.
