Abstract

PURPOSE: To enable the detection of abnormal lighting immediately prior to possible disconnection of a lamp by emitting a warning when a light signal deviates from a specified value in the difference from the other signal at the lighting of a lamp after inputted from a light detecting means at the start of a vehicle.
CONSTITUTION: At the start of a vehicle, light near a lamp to be detected is detected by a light detecting means composed of an optical fiber 9 and a photoelectric converter 10 and this first light signal is inputted into a microcomputer 13. Then, the lamp is lighted by the computer for a specified time from the inputting while a second light signal is inputted from said light detecting means. When it is determined that the difference between both the signals deviates from the preset normal range, a warning is emitted with alarm indicators 15, 16 and 17 to inform of the disconnection of the lamp.
