Vehicle lamp

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.

Vehicle lamp system and light distribution controller

A light distribution controller controls a light distribution variable lamp including a plurality of pixels arranged in an array. The processor executes the software program to generate at least one image defining the light distribution of the light distribution variable lamp, and writes the image in the volatile memory. A monitoring microcontroller detects an abnormality of the processor. A hardware logic circuit (i) generates a light distribution image data to be output to the light distribution variable lamp on the basis of at least one image written in the volatile memory in a normal state of the processor, and (ii) generates a light distribution image data on the basis of the generated auxiliary image without depending on the processor in an abnormal state of the processor.
