A torch includes a head member with a bulb unit, a tail member with a cell unit, and an intermediate flexible hose member interconnecting the tail and head members. The bulb unit includes an elongated bulb-holding seat made from an insulated material which has a front end wall, a rear end wall, a C-shaped-cross-sectioned intermediate section which interconnects the front and rear end walls securely, a bulb mounted on the front end wall, a conductive long stick which has a front end connected electrically to the bulb and a rear end fixed on the rear end wall, a conductive front short stick which has a front end connected electrically to the bulb and a rear end, and a conductive rear short stick which has a front end spaced apart from and adjacent to the rear end of the front short stick and a rear end fixed on the rear end wall. The tail member includes a cell unit for supplying power to the bulb unit. The hose member has a conductive front contact set in electrical contact with the rear ends of the long stick and the rear short stick, and a rear contact set in electrical contact with the terminals of the cell unit. Actuation of a switch can interconnect the rear ends of the long stick and the rear short stick each other.
