Thank you all guys who responded my posts about flashing led using IC HEF4093B circuit diagram. Following your advises I have achieved to operate it as should be. Now, flashing at dark but standby at light with draining very low amper as such 0,40mA and 0,045mA respectively. We may close this tread.
