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 bicycle light system has front and rear (white and red) lights with mounting brackets to secure on a bicycle helmet. A battery is contained in the rear light casing, with an electrical cord extending between the front and rear light casings. The front light casing has controls for both front and rear lights, which can include different power levels and preferably a flash mode for the front light. Helmet or headstrap mountings for the front and rear light casings have a quick-release feature enabling the lights to be easily and quickly removed from the helmet or headstrap, such as for recharging. Multiple selectable lights can be included in the front light assembly. In an embodiment, any of a series of different front light assemblies can be plugged into the rear assembly. For marine use appropriate light colors can be provided.

An illuminating undergarment carries a series of illuminating devices for emitting light and presenting a glow from underneath an outer garment. The undergarment can be tailored in any suitable form factor, such as a slip for placement under a skirt or skirt portion of a dress or other form factors for use under dresses, blouses, pants, etc. The undergarment comprises a series of illuminating device retention members affixed to a surface of the undergarment body. The undergarment body can be sectioned into segments, enabling changes in length and/or shape. The illuminating devices are removably attached to the undergarment by the retention members. The illuminating devices can be arranged in a random pattern, a pattern representing an object, a pattern representing text, etc. and any combination thereof. The illuminating devices can be powered by a portable power supply and controlled by a circuit and/or a switch.

A portable light device includes a headlight disposed at one end of the portable light device. The headlight is adjustable and can be directed to a variety of angles. The headlight includes a reflector with facets and at least one light source positioned approximately in an optic center of the reflector. Further, the portable light device includes a floodlight panel disposed at a front side of the portable light device. The flood light panel includes one or more light sources and each light source is covered by a primary optic.

In one aspect, a lighted tip for attachment to a flexible rod comprises a tip body having proximal and distal ends, a mechanical connector at the proximal end, a lens connected to the distal end, a light source that emits light through the lens, and a holder coupled to the light source and the lens. A circuit is completed or interrupted as the holder moves in relation to the tip body, thereby switching the light source on or off. In another aspect, a lighted tip for attachment to a flexible rod comprises a lens forming a distal end of the lighted tip. The lens is cylindrical over at least some of its length, and the tip further includes a light source at least partially within the cylindrical lens portion and a mechanical connector at a proximal end if the lighted tip, for connecting the tip to the flexible rod.
