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 modular system of light strips is configured for use on a roadway surface. The light strips are configured to withstand vehicular traffic driving over the light strips. The light strips have a rigid, durable housing protecting a series of LEDs within the housing. LED lenses direct light from the LEDs through the sidewall of the housing at vehicular traffic on the roadway. The channel is filled with a protective material, such as a polymer resin that protects the LEDs and power supply. The modular system includes a power source or can connect to a power grid. The modular system can include a sensor to activate the system and/or to control the light brightness Preferably the light strips connect together or can be substituted for one another to be interchangeable and easily carried, moved, installed and disassembled.

A safety light device includes a body defining a central bore and having a generally annular shape, a pair of teeth configured to extend into the central bore in an extended position and retract into the body in a retracted position, a charging system configured to charge a battery, and a plurality of light-emitting diodes (LEDs) disposed on an outer portion of the body.
