This is probably the simplest idea to generate flashing light from an LED using AC. The circuit is relatively the simple way of flashing one or more LEDs from a high voltage DC obtained from Mains. This can be used as a Mains indicator or Mock flasher.
The brightness of a neon tube can not adjust as easily as that of a bulb with Incandescent tube because it starts only when a voltage much higher than that of the network, then remains on at electrical network voltage.
Normally, the high starting voltage is obtained by the interruption of current which circulates through a choke coil. This is usually a starter to ensure a sufficiently large current through the tube filaments.
These starter functions are taken over by circuit presented which also allows adjustment of the neon brightness.
