A retractable peg system for a motorcycle including a bracket operatively attachable the motorcycle and a peg rotatably coupled to the bracket and rotatable between a retracted safe storage orientation and an extended use orientation. The system comprises a mobile node, a first and a second packet switching node. The adaptive filter may have adaptive filter coefficients and be configured to develop an adaptive error signal as a function of the adaptive filter coefficients. A housing directs the beam of light and an integrated circuit controls illumination of the plurality of light sources, with a switch providing an input signal to the integrated circuit. An interlevel dielectric layer is formed over the base contact layer and the emitter structure.
