After turning on the light, the test pen does not light up when it touches both, indicating that the live wire is disconnected.

There is no power when the switch is off, but there is a possibility that it will power you when it is on!
There is little chance of leakage. Basic security. Except: >>>More
There are several reasons why the light won't come on: 1 The light is broken. >>>More
Power off is a must If you are not very clear about the direction of your household appliances or the method of connection, it is recommended that you close the main gate in the distribution box This is the safest because some masters may connect the switch to the zero line when the installation is not standardized, and the switch is only turned off The zero line is turned off In this case, when you only turn off the switch, the phase wire (usually called the live wire) is not cut off, so there is still electricity on the lamp, so you must also turn off the main switch (in fact, the shunt air switch of the distribution box is also separated) I hope my answer will be helpful to you.
