Abstract

An electronic blinker circuit for a vehicle has an analog relay control section (24) and a digital circuit control section (25) arranged in a housing having only eight terminals. A holding circuit in the digital circuit section prevents an unintended oscillation when relay contacts are opened while a manual warn-blinker switch is still closed. When the engine ignition is switched off the blinker circuit requires a low quiescent current flow that is typically only 10 .mu.A.
