Transistor Q1 and transformer T1 form the oscillator with frequency about 15kHz, and the oscillation signal is boosted by the T1 secondary, rectified by diode, storaged by C1 to be about 300V DC voltage. Neon bulb, SCR, L2, etc. constitute a time interval trigger circuit. When the charging voltage on the capacitor C2 is up to the neon bulb starter voltage, starter current will trigger SCR to get transient conduction, so the discharge of C2 can get ten thousand volts after boosting by T2, then it will trigger the flashing tube to discharge and emit strong light. With the charge and discharge of the C2, the flashing tube will flash at a certain frequency rhythm.
