You can easily activate the LED from home electrical power line with this circuit diagram. You just need to add a nonpolar capacitor and a 1Kohm / 1W metal oxide resistor to activate the LEDs from home power line with serial connection.
Note:
Change the capacitor value from 0.47uf/250V to become 0.22uF/400V for 240VAC power line input.
Use safety tools, be carefull during installation since it use high electrical voltage.
