Vehicle light apparatus

A vehicle light apparatus includes a diffuser (3), a light-emitting unit (4), a light guide member (5), and a light control unit (6) to switch the light-emitting unit (4) between driving light and decorative light modes. The light-emitting unit (4) provides an illuminating effect or a warning effect when operating in the driving light mode. The light-emitting unit (4) in the decorative light mode emits a light color different from that emitted in the driving light mode. The light guide member (5) guides light rays from the light-emitting unit (4) to exit from the diffuser (3).
