Abstract
A vehicle lamp includes a semiconductor light emitting device as a light source, a power supply module configured to supply electric power from a power source to the semiconductor light emitting device, and a housing in which the power supply module is accommodated. The semiconductor light emitting device is mounted on the power supply module. The power supply module comprises a current control circuit configured to control an amount of current supplied to the semiconductor light emitting device. The semiconductor light emitting device and the current control circuit are arranged to overlap each other in a direction of an optical axis of the semiconductor light emitting device.
