<p>PROBLEM TO BE SOLVED: To easily detect a defective lamp by electrically connecting in series at least some from a plurality of lamps in a circuit arrangement for direction change indication lamps for an automobile. SOLUTION: Lamps 6-13 related to a directional change indicator on one side of an automobile are divided in groups 2 to 5 for each part disposed in the automobile. The group 2 comprises the lamp 6, the group 3 comprises the lamps 7 to 10, the group 4 comprises the lamps 11, 12, and the group 5 comprises the lamp 13, respectively. The lamps 6 to 13 are driven by a relay 1 for the direction change indication. At the time, for example, the lamps 7 to 10 as lamps in an electric lamp assembly provided integrally in an automobile external mirror, are connected in series so that in the case a defect is generated in one of them, for example, in the lamp 7, inflow of the electric current into the other lamps 8-10 is prevented for enabling easy recognition of the defect generated in the lamp.</p> |
