Abstract
A vehicle lamp includes: a first light source; a second light source; a first input terminal that receives a first turn-on instruction signal of the first light source; a second input terminal that receives a pulsed second turn-on instruction signal of the second light source; and a turn-on circuit that drives the first light source and the second light source based on the first turn-on instruction signal and the second turn-on instruction signal. The turn-on circuit includes: a drive circuit that becomes active based on the first turn-on instruction signal and the second turn-on instruction signal, and outputs a constant drive current from an output terminal; and a distribution circuit that forms a current path such that the drive current flows to the second light source, and forms a current path such that the drive current flows to the first light source.
