Abstract: A foot board with luminous structure for an automobile or a motorcycle includes a foot board, a translucent plate, a luminous module and a connecting member combined together. The foot board is formed with a fit opening in the center, the luminous module is positioned at one side of the translucent plate by the connecting member, and the translucent plate with a certain thickness is set in the fit opening of the foot board. Thus, when the electric source of the luminous module is started, the light of the luminous module will be irradiated on the translucent plate and simultaneously, the thick translucent plate will magnify the light and give out flickering light. Different from conventional foot boards, the foot board with luminous structure of this invention is novel in design and interesting in use.
