<p>PROBLEM TO BE SOLVED: To provide a lighting fixture for a vehicle suppressing increased total height dimensions and depth dimensions to eliminate a problem of heat in the lighting fixture having a lighting circuit of a discharge bulb. SOLUTION: In a headlamp integrally constituting a high beam lamp HHL for running and a low beam lamp LHL in a single lighting fixture body 1, providing a discharge bulb 16 as a light source of the low beam lamp and forming its depth dimension larger than that of the high beam lamp, behind the high beam lamp in a short side of the depth dimension, cases 30, 40 of a lighting circuit for lighting the discharge bulb 16 are arranged. The increased total depth dimension of a lighting fixture is suppressed, and weight balance of the lighting fixture itself is improved. The lighting circuit cases 30, 40 are formed to be divided into a primary/secondary side, so as to enhance respective heat radiation, a bad influence due to mutual interference of the heat between the lighting fixture and the lighting circuit is relaxed.</p> |
