Abstract: Disclosed is a directional warning light designed to bend along its longitudinal axis up to about 30° so as to conform to curved vehicle surfaces. Flexible components of the disclosed embodiments allow the bending and include a bendable optic, bendable base, and bendable circuit substrate.

Abstract: A hub-mountable wheel-rotation detector has an electromagnetic generator to convert rotational mechanical energy into electrical energy sufficient to recharge an internal rechargeable battery and power internal alarm and distance-tracking circuitry. The detector provides a combination of backup alarm and hubodometer functionality in a common device.

Abstract: A horn speaker improves ambience and sound quality by minimizing the transmission of sound diffusion and noise while maximizing the transmission of source sound generated by a speaker unit. The sound emitted by the speaker unit is collected in a seating groove and discharged through a discharge outlet of the horn speaker by integrally forming a plurality of horns in primary and secondary cases of the horn speaker enclosure. A simplified structure reduces the size of the horn speaker and difficulty associated with its assembly. The reproduction band of sound can be extended by forming a horn in a duct structure and adding sound pressure by combining it with sound emitted from the resonance of the duct in forward and backward directions. The amplitude of the resonance point is reduced in the same band and consequently advantageously reduces distortion of the sound.

Abstract: A mobile device software app facilitates a user's identification of a product suitable for various vehicle types and operating environments. The app configures a sensor in the device to sample ambient sound or light in the vicinity of the vehicle, calculates an intensity level value for the sample, compares the value to a list of specification intensity values corresponding to vehicle accessory products, and generates a list of products having intensity values greater than that of the sampled sound or light. The app optionally provides for user selection of a product and for viewing product literature. Users can also access detailed technical installation information, listen to sound samples, and locate product vendors.

Abstract: A vehicle-mountable track-lighting light bar (16) supports multiple light modules (5) in user-configurable mounting positions, each of the multiple light modules having a mounting foot (160), electrical contacts (300), and laterally extending track-attachment members (330). Multiple laterally spaced-apart electrically conductive pathways (274) are supported on a floor of each of light module mounting tracks (110, 112, 114). A light module, when its mounting foot is set in a light module mounting track, is slidable lengthwise along the track length while its electrical contacts contact associated ones of the electrically conductive pathways. A controller (276) is electrically associated with the electrically conductive pathways so as to apply electrical signals for delivery to the electrical contacts of the light module.

Abstract: A ball-and-socket joint module (26) affixed to a mirror head (14) provides for adjusting a position of a mirror (16). The module includes a multicomponent ball assembly (86) that has an internally mounted spring (82). The spring presses two components (34, 72) of the ball assembly away from each other so that opposing surfaces (32, 70) of the ball assembly confront corresponding surfaces (62, 64) of a multicomponent socket assembly (90) when the ball assembly is nested within the socket assembly.
