Abstract

PURPOSE:To produce an alarm by providing a detection circuit for varying time constant through utilization of differential voltage drop across a semi-conductor switch, thereby detecting breaking of wire of a direction indicating lamp in a vehicle and the like and varying flickering period thereof. CONSTITUTION:Upon connection of a switch (f) with a terminal L or R, a power source circuit (b) is started up through a battery (e) and an indication lamp (g). Consequently, gate signals are fed with predetermined period from an oscillation circuit (d) to a semi-conductor switch (a) so as to turn the semi- conductor switch (a) ON/OFF thus flickering the indication lamp (g). Difference between voltages V1, V2 [where, V1 is the voltage across the semi-conductor switch (a) when it is turned ON, while V2 is the voltage across the semi-conductor switch (a) when one line of the indication lamp is broken] is detected through a detection circuit (c) and fed to the oscillation circuit (d). Consequently, ON/OFF of the semi-conductor switch (a), i.e. flickering period of the indication lamp, is varied to alarm breaking of one line.
