An illumination device adapted for attachment to a surface of a rotatable
wheel comprises a rigid body having a substantially flat surface to which
is attached an adhesive material effective to adhere the illumination
device to a desired position on the wheel surface. The illumination
device also comprises a light source, a power source, such as one or more
batteries, and an electrical circuit that includes a switch for closing
the circuit to result in production of light by the light source. The
switch may be a motion-activated switch, a simple on-off switch, or other
suitable types. In embodiments disclosed, a cavity in the rigid body
holds the batteries, and a lamp cover houses the light source (and
selected elements of the electrical circuit).The invention also is
directed to forming a lighting pattern on a wheel by positioning such
illumination devices on selected positions on the wheel, and activating
them to create a desired lighting pattern.
