Abstract: A backpack for motorcyclists provides a rigid outer shell with an electrical system wherein an onboard battery powers rear signal lights, each comprising a plurality of light emitting diodes (LEDs), which are linked with the motorcycle's electrical system to function as brake lights and turn signals. The electrical system also charges a cellular telephone or other portable device via a Universal Service Bus (USB) port, and may be recharged by one or more solar panels mounted to the exterior of the backpack. A cellular telephone, music player, or similar device may also be connected via the USB port to play digital music files via speakers provided by the backpack, and a headphone socket is also provided. An onboard mapping device or homing beacon, enabled by the Global Positioning System (GPS), may be optionally provided.
