A vehicular marker lamp including an auxiliary light emitting portion disposed near a tail/stop lamp (a main light emitting portion) having a red exterior appearance which is a lamp function color of the tail/stop lamp. The auxiliary light emitting portion is structured by a colorless and transparent light guide plate and a plurality of red light emitting diodes disposed so as to allow light from the light emitting diodes to be incident to the light guide plate so that when the tail/stop lamp is lit the light guide plate emits red light by the light which is incident from the light emitting diodes. |

DETAILED DESCRIPTION Accordingly, it is an object of the present invention to provide a vehicular marker lamp that is capable of securing sufficient light emitting area when the lamp is lit, even if the lamp chamber is compact.
The present invention accomplishes the object above by providing an auxiliary light emitting portion.
More specifically, the above object is accomplished by a unique structure of the present invention for a vehicular marker lamp that lights in a predetermined lamp function color and comprises a main light emitting portion, which has a predetermined chromatic exterior appearance and lights with the lamp function color, and an auxiliary light emitting portion, which is disposed adjacent to the main light emitting portion; and the auxiliary light emitting portion is provided with a substantially colorless and transparent light guide plate and a light source disposed such that light thereof is incident to the light guide plate, the auxiliary light emitting portion being structured such that, when the main light emitting portion is lit, the light guide plate emits light with a color that is substantially identical to the lamp function color of the main light emitting portion by light incident from the light source.
The specific type of the "vehicular marker lamp" is not particularly limited.
For example, a tail lamp, stop lamp, tail/stop lamp, turn signal lamp, and the like can be the "vehicular marker lamp," and the vehicular marker lamp may be a combination lamp or the like equipped with a plurality of lamp functions.
The "lamp function color" signifies an emitted light color required to fulfill the lamp function of the vehicular marker lamp when the lamp is lit.
For instance, red in cases where the vehicular marker lamp is a tail lamp is the "lamp function color", and the "lamp function color" is amber when the vehicular marker lamp is a turn signal lamp.
The specific structure of the "main light emitting portion" is not particularly limited as long as it includes a predetermined chromatic exterior appearance and lights in a lamp function color
