The invention relates to a life preserver's lamp provided with a hand-actuated switch and a singular safe fuse 2 differentiating said lamp from those existing on the market. Forcing of the safe fuse 2 may be induced by extended anticlockwise rotary force applied on the upper translucent plastic shell of the lamp (fig. 3) and the surface 1 thereof being much thinner at the circumference of its base (fig.5). Thus detached from the main body, it leaves a through hole and abolishes the operation ofthe lamp covering in this way the requirements of the international regulations. The advantage of the invention is that the inside accessories of the lamp are protected from any modification intervention so that the initial constructional propertiesof the lamp structure remain unalterable to ascertain its safe function leading to the desired results. |
