In USA you can buy at most hardware stores an adaptor that fits in to the holder that takes standard USA bulb.
All you do is take out the bulb and screw the adaptor and then screw the bulb. The switch must me left in on position.
There is a switch available that does the same thing, you just have to swap the switch. This may be even batter, switches are very likely compatible between the systems.
If you still want to re-invent the wheel then all you need is to have LDR in series with the source or switch or the bulb.
Experimentally it may be good to create your own, but the ready made package meets all the codes and it is a very good looking in appearance, compact and convenient.
PS
I hope you have a bench to experiment on. You Will also need a lamp, a fuse box on the bench or an extra power strip with circuit breaker.

Use light dependent resistor (LDR) as a sensor. The LDR must be part of a voltage divider circuit in order to give an output voltage, Vout , which changes with illumination.
