Sub: Application for Tube Light Replacement
Sir, I am (Name) and I am a student at your prestigious university. I am also living in the dormitories provided by the university. I am very pleased with the neatness and cleanliness of the dorms. I was studying in my room yesterday and suddenly the light went out. (show your actual problem and situation). I turned on the emergency light and looked for the fuse only to find out that the tube light has been burnt out. The light in my room is very low now and it is very hard to study with that. Therefore, I request you to please send an electrician to get that tube light replaced. Thank you,
