When the oscillator begins to work, 300V high-frequency pulse voltage will be generated on W3. The voltage will be divided into four circuits after rectification. One will be put on the flash light's A terminal directly. One will charge C4. One will charge C3 through R2,R3. One will charge C2 through R2,R4,R5. When C2-C4 stop charging, V2, VT will be connected. C3 will generate high voltage on T2. The voltage will be put on B,C. Then C2-C4 will be charged quickly. Everytime the brake switch is connected, the flash light will twinkle many times.
