has this happened to anyone else? today when returning home from a ride i noticed my high-beam indicater on, even though the switch was on lo-beam. when i pulled into the garage i noticed the headlight out.after checking all wires and connections and fuse, the culprit was the light itself. my qustion is, is the high-beam indicater a sort of warning light for the headlight being burned out? i replaced the headlight now everything is back to normal. the bike is a 76 cb550k.
