PROBLEM TO BE SOLVED: To improve a verification and recognition characteristics of a signal lamp and also improve appearance. SOLUTION: A reflection surface 70 is on the opposite side of a lens 3 with respect to a surface V-V which passes adjacently to filaments of color bulbs 5B, 5C, and is orthogonal to an optical axis Z-Z. As a result, in reflection surfaces represented in Figure 13 and Figure 14, only an inside reflection surface 92 is used. Therefore, functional colors of the color bulbs 5B, 5C reflected on the reflection surface 70 are made less thinner by a metallic color of the reflection surface compared with conventional signal lamps, and the functional colors of the color bulbs 5B, 5C reflected on the reflection surface 70 appear deeper through a clear lens 3 compared with the conventional signal lamps, thereby verification and recognition characteristics of the signal lamp are improved. The color bulbs 5B, 5C are presented on backgrounds of deep functional color, and the presence of the color bulbs 5B, 5C are camouflaged by the backgrounds of deep functional color, thereby the appearance is improved.
