A location device is provided, in which the device is configured to be carried by a tire and wheel assembly so as to locate a right or left position of the assembly in a vehicle. A poly oxide layer is formed over gate electrodes on a semiconductor body and active regions defined within the semiconductor body in PMOS and NMOS regions. The non-uniform contour may be placed directly on the tubular envelope forming the lamp or may be formed on a separate envelope enclosing a conventional cylindrical tubular germicidal lamp. As a result, a user may connect a device to the system bus without having to determine which communications protocol is used by the system bus.
