A hand holdable light comprises: a light body having a forward portion, a rearward portion, and a central portion between the forward portion and to the rearward portion; a light source proximate a forward end; and a switch for energizing the light source. The rearward portion has a non-circular cross-section; the switch is on the forward portion; and the central portion has a recess opposite the switch. The light is holdable by a hand with a finger or thumb proximate the recess and the other of a finger or thumb proximate the switch. A battery assembly comprises: a battery housing for receiving and connecting a battery; an electrical switch on a first end of the battery housing; and a pattern of electrical contacts on a second end of the battery housing, wherein ones of the electrical contacts are connected to the battery.

A mountable light includes a light body and a mounting arrangement including first and second clamping members from a set of pairs of clamping members. The light body has first and second opposing receptacles in which the respective clamping members are respectively removably disposed to move toward and away from each other. One clamping member may be fastened in its receptacle so as to be a fixed clamping member while the other clamping member is movable. A clamping mechanism may move the clamping members closer together to engage a mounting rail or away from each other to release the rail. An interchangeable key member may be provided between the clamping members, and may be selected from a set of interchangeable key members.

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.

A flashlight for use with a pistol, the pistol having a trigger guard and a mounting rail. The flashlight includes an elongated housing having a spring arm clamping mechanism for mounting to the mounting rail, a light source at one end thereof, and paddle switches at an opposing end.

A utility light mountable to a workpiece. The light includes a main body having a length extending between a first end and a second end, a light assembly, and a battery. The battery is removably coupled to the first end. The light further includes a first handle coupled to the second end and a second handle movably coupled to the first handle. The second handle is linearly extensible relative to first handle along a direction perpendicular to the length between a retracted position and an extended position. In the extended position, an opening is defined between the second handle and the main body. The opening is configured to receive the workpiece to support the utility light when the handle is in the extended position. The light assembly is disposed above the battery and below the first handle with respect to a direction along the length of the main body.

A utility light mountable to a workpiece including a main body having a first end, a second end opposite the first end, and a length extending between the first end and the second end. A light assembly is coupled to the main body and has a light housing and a light source disposed within the light housing. The light housing is pivotable and rotatable relative to the main body. The utility light further includes a battery support portion configured to selectively receive a battery. The battery support portion disposed at the first end of the main body. A handle assembly is coupled to the second end of the main body. The handle assembly has a first member configured to be grasped for carrying and maneuvering the utility light and a second member that is moveable relative to the first member.

A pocket carried work light has an elongate body with a first end, a second end, and defines a medial channel extending between the ends, the medial channel carrying a battery. A first electrode in the medial channel that electrically communicates with the battery and an electric circuit, a second electrode in the medial channel that communicates the battery and with the electric circuit and a switch communicating with the electric circuit. A pocket clip carried by the body and extending spacedly adjacent and parallel thereto, the pocket clip carrying a low intensity LED on a second surface opposite the body, the LED electrically communicating with the circuit to emit light waves when the electrical circuit is completed by operation of the switch.

A compact light device includes a housing containing an integrated circuit board having a number of components thereon including at least one high CRI LED, a timer for controlling illumination time of the LED, and a switch for activating illumination of the at least one LED. A front face of the housing has openings for receiving lens covers for each LED and an actuator button for operating the switch on the circuit board. A removable spring biased clip allows the light device to be conveniently attached and removed from all types of articles and objects. A battery drawer slides out from the housing to allow replacement of batteries used for powering the components on the circuit board. One or more adhesive pads on the bottom of the housing enable mounting of the light device to any flat surface.

Spectacles with an illuminating light having a quick-release structure are provided. A clip piece of a clip member is inserted through a through hole of a temple, and the clip member can be rotated and operated. The clip piece is adapted to clip an inner surface of the temple and a buckle hole of the clip piece is engaged with an engaging protrusion on the inner surface of the temple, such that the illuminating light is secured on the temple. On the contrary, the illuminating light can be quickly removed from the temple. The overall structure can effectively enhance the convenience of the use of the spectacles for the installation of the illuminating light.

An apparatus for a lighting device with a rotatable support includes a lamp body, the lamp body is provided with the support capable of rotating relative to the lamp body, the support is provided with a magnetic block, and a lighting port of the lamp body is arranged on the side wall of the lamp body toward the direction of the rotation center line of the support. When the adjustable lighting device is used, the support is fixed on a metal object in a place to be illuminated through the magnetic block and the side face direction of the lighting port of the lamp body can be adjusted by adjusting the lamp body to rotate relative to the support, and therefore the side face lighting angle of the lighting port is adjusted, and due to the fact that the lamp body can rotate relative to the support at any angle, stepless adjustment of the side lighting angle of the lighting port can be achieved.
