Are you want to know How to make easily auto ON/OFF Rechargeable Emergency light then this post will be helpful for you. Actually, we are going to know two things Inside an Emergency Light and How to make easily auto ON/OFF Rechargeable Emergency light. 

            Internal parts and circuit diagram of an Auto ON/OFF Rechargeable Emergency light are given below. So using this circuit diagram you can make easily auto ON/OFF Rechargeable Emergency light. The circuit diagram is very simple.
 
                At first, let's see what inside an auto ON/OFF Rechargeable Emergency light. As you see in the picture there is a LED panel, a Transformer, and a simple circuit board in the Emergency light.

                       Here a 9V-0-9V Center trapped Transformer is used for step down the voltage 230V to 9V. Diodes are used for make rectifier circuit. A 12V relay is used for automatic of the led when it connected to the power supply and in this time battery is charging. When the emergency light unplugged from the power supply automatically Led will be glow and the LED takes power from the battery. See the below circuit diagram for better understanding.
