Friends this is very simple circuit to flash LED on 220 volt ac directly. In this circuit we will use transistor collector and emitter and leave the base . 

If u need more speed for flashing use 220uf capacitor and if you need slow speed use 1000uf or 2200uf capacitor . please see video for detail
