Claims

[Scope of Claim for Utility Model Registration] In a headlamp wiper circuit that forms a driving circuit for a washer motor via a contact plate rotated by a wiper motor, a part of the driving circuit for the washer motor includes:
The contact side of a relay consisting of a contact and a coil is connected in series, and the coil side of the relay is connected in series to a washer fluid level sensor circuit which is provided in parallel with the washer motor drive circuit. A headlamp wiper circuit characterized in that a drive circuit for the washer motor is cut off via a relay when the remaining amount of the washer motor reaches a predetermined level.
