CEV  Eletrical  Switch That  Fits in  Headlight  Bucket,  BAT/DIN

NOS CEV headlight switch for bikes with generators. This switch fits in the headlight bucket and toggles between running your bike of the battery or generator. Basically a emergence start switch that lets you start your bike off the generator if you have a dead battery. Found on Benelli 4-stroke singles and probably some other Italian bikes too.
