Abstract
A lamp ECU can control an additional lamp. A connector includes a power supply pin that receives battery voltage ECUB from a vehicle, a communication pin connected to a vehicle bus, and an output pin to be connected to an additional lamp. An output node of a power supply circuit is connected to the output pin and outputs power supply voltage from the output node in an enabled state. In a first mode, a first controller controls the enabled and disabled states of the power supply circuit according to a turn-on/off instruction for the additional lamp received via the vehicle bus. In a second mode, a second controller controls an output interface circuit according to the turn-on/off instruction.
