<p>PURPOSE:To securely give rectilinear advance sign to a car running in the opposite direction by disposing a device body consisting of a main lamp and peripheral multistage lamps surrounding the main lamp on the central front end or the like of a car body to light sequentially said lamps from the outermost one to the main one and repeat the lighting sequentially. CONSTITUTION:A device body is constituted from a large main lamp 3 having high light intensity and a plurality of side light lamps 4-6 surrounding concentrically main lamp 3. And the lamps 3-6 are provided with reflective plates 7 and colored lenses 8 respectively. Also, the lamps 3-6 are respectively connected to a drum type lighting controller 9 and a slide plate 11 for the main lamp 1 is provided on a drum 9' rotated by a micromotor 10 in the controller 9. On the other hand, side lamps 4-6 are respectively provided with slide plates 12-14 to open and close contacts with the rotation of drum 9' at intervals of time for flushing lamps. Thus, the drum 9' is rotated by the turning-on operation of switch 15 so that the lamps are lit sequentially from the outermost side lamp 6 to the main lamp 3 and the lighting is sequentially repeated.</p> |
