ABSTRACT:
In the disclosed device, a DC-DC converter boosts the output of a battery to charge a capacitor that stores electrical energy to be converted into light energy and turns on a neon tube when the capacitor voltage reaches a first predetermined value. A control arrangement disables the converter in response to the neon tube turning on the re-enables the converter when the capacitor charge drops to the first predetermined level after the neon tube turns on.
