Abstract: An emergency taillight for a vehicle includes a reflective housing with a transparent cover and a light source resiliently suspended in the focal center thereof. In the first embodiment, the light source is energized by a periodic source of electrical power to provide the impression of flickering light both during the movement of a vehicle as well as when it is standing still and no vibration is transmitted to the resilient suspension means of the light source. According to the second and third embodiments, electromechanical means are provided to cause the oscillating motion of the light source even when the vehicle is not itself in motion. The invention provides for a better attraction of the observer to the emergency light in poor visibility conditions regardless of the presence of vehicle motion. One or more light bulbs, LEDs, or laser light diodes may be used as a source of light for the emergency light of the invention.
