Abstract
To eliminate the need for a cap provided only for coloring the light of a wedge-base bulb, and to eliminate the requirement for a multi-colored front lens of a vehicle identification lamp, a colored coating is formed on the surface of a glass bulb of a wedge-base bulb. The bulb is dipped in a color coating and a rib and/or groove is provided between the bulb and a base portion of the wedge-base bulb to prevent the coating from adhering to the base portion where terminals are disposed.
