PROBLEM TO BE SOLVED: To provide a light source for a lighting fixture for a vehicle having high quality.SOLUTION: A light source for a lighting fixture for a vehicle has a first semiconductor light-emitting element, a second semiconductor light-emitting element and a drive device for performing AC drive of the first semiconductor light-emitting element and the second semiconductor light-emitting element. A p-side electrode of the first semiconductor light-emitting element and an n-side electrode of the second semiconductor light-emitting element are electrically connected to each other, an n-side electrode of the first semiconductor light-emitting element and a p-side electrode of the second semiconductor light-emitting element are electrically connected to each other. The first and second semiconductor light-emitting elements are arranged in one direction, and the drive device performs the AC drive so that time when a current passes through the first semiconductor light-emitting element and time when a current passes through the second semiconductor light-emitting element are different from each other.SELECTED DRAWING: Figure 3
