Abstract: A propeller blade assembly including a propeller blade having a leading edge, and a trailing edge extending between a tip and a hub, and an electrically conductive band extending longitudinally on either or both of the leading edge and trailing edge. The electrically conductive band secured to the leading edge of the propeller serves as an entry point on the aircraft and conductive channel into the airframe thereby avoiding the potentially damaging effect of the lightening on the carbon fiber composite propeller.

Abstract: A system for flashing a plurality of light sources, such as the headlights, taillights, brake lights and/or turn signal indicators of an automotive vehicle which includes a plurality of light switching circuits wherein one light switching circuit is associated with each light source. Each light switching circuit is responsive to a predetermined input signal to switch its associated light source between an on and an off condition. A microprocessor has a plurality of output signal lines wherein one output line is electrically connected with each light switching circuit. The microprocessor is preprogrammed to generate the predetermined input signals to the light switching circuits on its output signal lines in a predetermined sequence.
