A visual distress signal device that generates and emits bright light and/or infrared light to alert bystanders during times of distress. The device may be particularly suited for use on boats. The device may comprise a heat sink assembly that includes a screw-on collar that is attached to a housing of the device, such that the screw-on collar dissipates heat generated by electromagnetic radiation emitting elements away from an interior of the housing. The device may be configured for activation by a mobile phone or other mobile device which may be connected to the device via wireless communication. Furthermore, the mobile device may comprise a software application that can be used to alert persons in a contact list regarding the user's location and emergency status.
