Abstract
A flashlight usable as an extensible signal bar includes a casing, a switch housing containing a push button connected with a T-shaped conductor elastically urged by a double conical spring housed in a short tube, a lamp holder located in front of the switch housing in the casing, a lamp housing protecting a lamp and a reflector in a rear portion and having a front hollow portion for combining an extensible signal bar. The extensible signal bar consists of a plurality of sleeves, which can be collapsed within the lamp housing or extended out thereof to form a fully extended signal bar to function as a warning means if needed.
