Turn off the light, will you/won't you?

Turn off the light, will you?
Don't call Andy, will you?

Would it be OK to use "won't you" as a tag in the sentences above? If so, would the meaning remain the same?

Not to me.

It doesn't matter if the main part is positive or not in imperatives: in either case the tag should be "will you", right?

BTW, is "right" in the last sentence also a tag?
