One of the more popular ways of forcing people to vacate their house is disconnecting the electricity supply to the main points where the bulbs are fixed.
So alternative lighting methods have to be used.
One of the more popular options is using rechargeable light bulbs
These bulbs function like normal light bulbs when there is electricity.
When the electricity supply is cut, they continue to provide illumination, manual intervention is not required.
However these bulbs are fairly expensive, costing Rs 600 per bulb
