PROBLEM TO BE SOLVED: To obtain a light-distribution pattern of two functions with one lamp device. SOLUTION: A light distribution pattern for foggy weather FP is obtained when a movable shade 6 is positioned at a first position with a driving means 7, and that for significant weather SP when the movable shade is positioned at a second position. As a result, light distribution pattern of two function is obtained with one lamp device, that is, light distribution pattern for foggy weather FP and light distribution pattern for bad weather SP. Therefore, there is no need of increasing space of installation of lamp devices even if the number of functions of light distribution pattern is increased, the number of lamp devices remaining the same. |
