Abstract: A multi-functional tactical flashlight that includes a case, a flashlight bulb, a high intensity flash lamp, at least one infrared sensor, and an indicator. The case has a bulbous head. The flashlight bulb is disposed in the bulbous head of the case and is selectively illuminated therefrom. The high intensity flash lamp is disposed in the bulbous head of the case and is selectively illuminated therefrom. The at least one infrared sensor is disposed adjacent to the bulbous head of the case and is selectively activated. The indicator is responsive to the at least one sensor and indicates when the at least one infrared sensor senses an infrared signal. The at least one infrared sensor can be only one infrared sensor or a matrix array of infrared sensors.
