Abstract
A vehicular lamp has a plurality of light source modules for emitting light. Each of the light source modules has a semiconductor light-emitting element, a lighting circuit operable to control an electric current flowing into the semiconductor light-emitting element to turn the semiconductor light-emitting element on and off, a power cable operable to supply electric power from a power source located outside the vehicular lamp to the lighting circuit, a control cable operable to transmit a control signal that controls turning the semiconductor light-emitting element on and off to the lighting circuit, and a mounting substrate that mounts the semiconductor light-emitting element and the lighting circuit. One of the light source modules is connected to the power source by means of said power cable. The light source modules other than the one light source module are connected to the one light source module in parallel via the power cable.
