PROBLEM TO BE SOLVED: To prevent so-called false lighting caused by incidence of external light of the sun and the like into the signal lamp. SOLUTION: A reflecting surface of a reflector 2 of a signal lamp for use in a vehicle 1 is formed in plural combinations with the first reflecting surface 2a, where a light source 3 forms a focal position F1 approximately, and the second reflecting surface 2b, where a portion of a socket 4 forms a focal position approximately. The socket 4 is colored into other color than a functional color as the signal lamp for the vehicle 1. Therefore, when the light source 3 is lighted, light from the light source 3 is reflected forward as almost parallel light at the first reflecting surface 2a, and light with the functional color as the original signal lamp for the vehicle 1 is emitted. When the light source 3 is not lighted, the color other than the functional color of the socket 4 is reflected at the second reflecting surface 2b. |
