An emergency signaling device for the hearing impaired provides a strobe light in which the intensity of the emitted light is variable. The emergency signaling device comprises a housing and a reflecting mirror coupled to the housing. A strobe light emitting device adapted to provide a sequence of flashing light is disposed in relation to the reflecting mirror so that the light is distributed in a predetermined pattern. The intensity level emitted by the strobe light emitting device may be varied between at least a first intensity level and a second intensity level. The reflecting mirror provides a polar light distribution of the flashing light. The rate of flashing of the strobe light emitting device may be synchronized with other emergency signaling devices.
