使わない時は消す。って英語でなんて言うの？

This is a way to nicely tell people to turn off the light when you are not using them. I hope that this helps :)

This answer is as basic as you would need to make this note. By adding the word 'please' to this request it makes it more polite. Without the 'please' the statement is still useable it is just more direct and more like an order rather than a polite request.

When someone leaves a light on, many times it wastes electricity and is bad for the environment. We want to make sure that we use only what is necessary to use. If a note is necessary to encourage colleagues, family, or coworkers about turning off the lights when they are not being used, there are some expressions that we can use on the note: 1) Turn off the light when not in use. 2) If you are not using the light, please turn it off.

Notices often miss out the articles (a, an or the) and use the imperative form. This may seem a little direct but the overriding objective is just to get the message across as briefly as possible.

Notes can be annoying to others who share the same space with you, but a smiley face or a little rhyme can soften the reminder.

"Please keep the lights off when not in use." This is a polite way of asking people to keep the lights off, if people are not using them. "Please turn off lights when done using them." This is another way of rephrasing the same sentence. Done means finished, or completed, and here it is saying that after using the lights, to turn them off.

When you want to place a note reminding people to turn off the light: -Please turn off the lightwhen not in use -Please remember to turn off the light when you're done -Remember: switch off the light when not in use.
