Abstract: A lighting device having a body includes a light assembly, an electronics subassembly, and a switch assembly. The light assembly is secured to the electronics subassembly at a front end of the body and the switch assembly is secured to the electronics subassembly at a rear end of the body. The electronics sub assembly houses, within a sealed internal volume, a battery and a circuit board. The switch assembly includes a switch button, a sealing boot and a wave spring.

Abstract: Embodiments of an attachment device for supporting a lighting device or other tool or accessory from a hat or helmet, or a kit including same, are shown and described.

Abstract: A lighting device that includes a body having a front end and a rear end opposing the front end, a light source, and a switch assembly that extends through the rear end of the body. The switch assembly includes a switch button, a sealing boot, and a wave spring. The wave spring is compressed between the switch button and the sealing boot such that the sealing boot covers an end opening of a subframe. The switch button has an actuator extending through the wave spring. The switch assembly is depressible such that the actuator engages the sealing boot and applies pressure to a switch member disposed within the subframe. When the switch member is actuated, a signal is sent to the light source.

Abstract: Improvements in portable lighting devices are shown and described. These improvements include new arrangements for the configuration of battery compartments to allow for different types of battery sources to be used therein, use of electromagnetic position sensing for a mode selection or other type of switch, selector, or dial, and improvements relating to venting of a battery compartment.
