A loading-dock signaling system includes an internal signal light, an external signal light and a wheel chock having a base and a handle extending from the base. A chock signal light is positioned on the handle. The internal signal light, the external signal light and the chock signal light are in signal communication with one another to provide at least a plurality of illuminated indicia to an exterior dock area and an interior dock area. The exterior dock area and the interior dock area are separated by a dock door.

Electronic light emitting flares and related methods. Flares of the present invention include various features such as self-synchronization, remote control, motion-actuated or percussion-actuated features, dynamic shifting between side-emitting and top-emitting light emitters in response to changes in positional orientation (e.g., vertical vs. horizontal) of the flare; overrides to cause continued emission from side-emitting or top-emitting light emitters irrespective of changes in the flare's positional orientation; use of the flare(s) for illumination of traffic cones and other hazard marking or traffic safety objects or devices, group on/off features, frequency specificity to facilitate use of separate groups of flares in proximity to one another, selection and changing of flashing patterns and others.

A life safety device includes a housing and a light transmission device disposed within the housing. A first end of the light transmission device is visible at the exterior of the housing. The life safety device additionally includes a transmitter for generating a light. The transmitter is positioned within the housing adjacent the light transmission device. A receiver measures ambient light around the life safety device. The receiver is positioned within the housing adjacent the light transmission device.
