  • Patent number: 6053626
    Abstract: A light emitting diode (LED) directional light bar assembly for use on a motorcycle includes a substantially rigid light bar having opposite ends. Apertures are defined generally adjacent each of the opposite ends by a rear-facing surface of the light bar. A lens is sized to fit at least partially within each aperture such that a surface of each lens is substantially flush with the rear-facing surface of the light bar. An LED pod including a plurality of LEDs is disposed adjacent each lens. Each LED includes a selected number of LED running lights wired to emit light during operation of the motorcycle, and a selected number of LED brake lights wired to emit light during operation of the motorcycle only when a motorcycle brake is applied. A retention plate or member is interconnected to the light bar generally adjacent each opposite end, and at least partially captures each LED pod and lens between the retention member and the light bar.

  • Patent number: 5738180
    Abstract: A footboard assembly including a resilient pad having a planar portion and a lip portion extending outward from the planar portion, and a cover member position over the resilient pad. The lip portion extends laterally outward further than an outer perimeter of the cover member. The cover member includes a plurality of openings, and the resilient pad includes a plurality of raised portions extending upward from the planar portion and through the openings. Shaker mounts are formed integrally with the resilient pad to provide vibration damping between the motorcycle platform and the footboard assembly. A substantially rigid insert is molded into the planar portion of the resilient pad. A thin layer of resilient material is positioned under the insert to completely enclose the insert.
