PROBLEM TO BE SOLVED: To change a light source from a bulb to an LED light source to use LED for lighting with a minor design change at a low cost.SOLUTION: A system 10 comprises: a first current limiting means 54 limiting current flowing through a first LED light source 24; and a second current limiting means 58 limiting current flowing through second LED light sources 26, 28. An operation switch 60 allows current to flow through the first LED light source 24, the second LED light sources 26, 28, and the first current limiting means 54 in a series at a high beam lighting time, and the second LED light sources 26, 28 and the second current limiting means 58 in a series at a low beam lighting time.SELECTED DRAWING: Figure 2 |
