An inner lens is provided behind the front panel having upwardly slanting sawtooth-like step reflecting structures formed on the front surface of the inner lens and a light-converging structure formed on the rear surface. A light directing plate having a reflecting surface is disposed behind the inner lens. A light source is mounted in a central thick portion of the light directing plate.
