Light on off by remote in #WARSAW TO #DELHI FLIGHT #WarsawToDelhiFlight

I travel in a polish flight from Warsaw to Delhi. I have seen sometimes in few flights the buttons of remote control of the asigned seat do not work and even our finger touchs on tv screen do not work. Light is important for reading any paper or book but flight captain or attendees switch the light in whole flight to very dim after lunch or dinner so travellers can sleep little bit. At this moment we have to know how to switch on or off using remote a light which is only focused to our asigned seat. This is shown in this video.
