Abstract
An automobile lamp includes a lamp seat, a lighting unit, and a light guiding member. The lighting unit is positioned on the lamp sear. The light guiding member is disposed on the lamp seat and covers the lighting unit. The light guiding member is formed with a plurality of ribs thereon. The ribs form a corrugated structure along the radial direction of the light guiding member. When a plurality of light beams are emitted from the lighting unit into the light guiding member, part of the light beams travels along the corrugated structure.
