Abstract: A method for selecting a mode/color on a lighting module, the lighting module having only a single button includes: receiving a first actuation of the single button at the lighting module. The method further includes responsive to the first actuation, turning the device on and displaying a first mode/color. The method further includes detecting that the single button is held down. The method further includes displaying a plurality of modes/colors in a timed sequence, such that each mode/color of the plurality of modes/colors is displayed for a preset time period. The method further includes detecting that the single button is released. The method further includes displaying a selected mode/color of the plurality of modes/colors that was displayed when the single button was released.

Abstract: An animal restraint is either a leash or a collar. The animal restraint includes a lighting module and a circuit board, the circuit board enclosed in the lighting module. The animal restraint further includes a first light source connected to the circuit board, such that the first light source does not have a fixed position in relation to the circuit board, the first light source enclosed in the lighting module. The animal restraint further includes a fiber optic connected to and receiving light from the first light source, the fiber optic at least partially in the lighting module. The animal restraint further includes a first flat strap, the fiber optic surrounded by the first flat strap.

Abstract: A glowstick includes a lighting module, the lighting module including a light source having a primary direction of emission. The glowstick further includes a polymer rod, the polymer rod interfaced with the lighting module, the polymer rod having a length, a depth, and a width, wherein the length is greater than the depth and the length is greater than the width, the polymer rod proximate to the light source such that the primary direction of emission of the light source is aligned with the length of the polymer rod.
