    Abstract: The specification discloses a floating marine safety light having a pressure actuated switch which enables the light to be carried or stored in an upright position with the circuit open and which will make contact to close the electric circuit to illuminate a safety light when the light is immersed in water. Further, the invention includes means for compensating pressure changes in the light to prevent accidental actuation of the pressure switch due to thermal fluctuations. The invention also includes means for impeding or retarding descent of the safety light when dropped from high elevations, such as from a low flying aircraft.
