Circuit maintains constant high-current level through lamp while lighted and a low simmer current through lamp while not lighted. Lamp current is switched between these two modes by transistor; transistor is therefore called current-mode switch. Stable light pulses are emitted from flashlamp when monostable multivibrator goes high, in part because unsaturated transistor switch has negative feedback control that keeps lamp current constant.
