  • Patent number: 9981595
    Abstract: Provided is a vehicle lamp including an optical unit including an optical element and a solenoid that drives the optical element; and a driving circuit configured to receive a voltage from a DC power supply and apply a driving voltage to the solenoid. The driving circuit includes a signal generating circuit that generates a notification signal indicating whether or not the solenoid is open-circuited. The signal generating circuit generates a first signal as the notification signal when the solenoid is normal. The notification signal is set as a second signal that is different from the first signal when open-circuit of the solenoid is detected.
    Type: Grant
