Abstract
A vehicular marker lamp such as a tail and stop lamp, including a translucent member extending substantially along a translucent cover which is red and transparent with first light-emitting diodes in the back and second light-emitting diodes near the side end of the cover. The translucent member has a direct light-emitting region that transmits light, which is incident to the translucent member from the first light-emitting diodes, toward the front, and indirect light-emitting regions that internally reflect light, which is incident to the translucent member from the second light-emitting diodes, so as to emit such light toward the front. The direct light-emitting region is a red transparent region, and the indirect light-emitting regions are colorless transparent regions, thus allowing the appearances of the direct and indirect light-emitting regions to be significantly different from each other when the lamp is lit.
