An illuminated vehicular emblem for a means of transportation includes a housing unit, a lighting unit and a light dimming unit. The housing unit includes a bottom case, a top case disposed on the bottom case, and an emblem member disposed above the top case. A receiving space is defined between the top and bottom cases to receive the lighting unit. The lighting unit includes a light guide plate, light emitting components and a first light shielding film disposed on the light guide plate. The light emitting components are disposed at the light guide plate such that the light guide plate receives light emitted from the light emitting components. The light dimming unit changes the direction of propagation of the light and includes a first dot portion distributed on the light guide plate and along a projection of an outline of the emblem member.
