PIC Indicator Relay

Members of the motorcycling fraternity will welcome this design. Some types of motor cycle are notorious for having very short life expectancy of their filament indicator lamps. Vibrations transmitted through the frame are the culprit (especially if the indicators are mounted on the ends of long stalks). After-sales replacement LED lighting clusters are far more reliable but they create another problem: they draw less current than the filament lamp and cause the indicator relay to switch the indicators on and off far too quickly.
