PURPOSE:To obtain highly reliable head lamp by detecting the sinking amount of chassis through an optical fiber then adjusting the irradiation angle of head lamp manually. CONSTITUTION:Vertical displacement of shaft 22 against the chassis is taken out through the transmission rod 16 and an arm 14 as the rotation of transmission shaft 12. Through said rotation the rolling member 6 rotates against the casing 1 thus to select the filters 91-93 facing with the bulb 4. When employing different color of filters 91-93, colored light corresponding with the displacement of the shaft 22 is applied through an optical fiber 24 on an indicator to indicate the displacement. In accordance with said indication manual operating section is functioned to adjust the irradiating angle of head lamp. Consequently unreliability or difficult setting of conventional device can be eliminated. |
