Driving flashing light circuit

KD OIX is a single crystal large integrated circuit that drives light bulbs and light-emitting diodes to flash. There are two flickering frequencies
: 1. 2Hz and 2.4Hz. Each frequency is determined by the internal circuit oscillation resistance, and no external resistor
or capacitor is required.
  This circuit is now used for flashing corsages, and can also be used for flashing indicators, idle light card issuance, glasses, cards,
gifts and other decorative toys, as shown in the figure. Performance characteristics of
  driving flashing lights
:   1) Low power consumption, saving electrodes;
  2) Two flashing frequencies: 1. 2Hz, 2.4Hz;
