The car is so old that replacing the engine is 'not worth the candle'. [=the effort isn't worth the cost]
The new movie doesn't 'hold a candle to' [=it is not as good as] the original version.
We came to the memorial to 'burn' [='light'] a candle for the victims of the accident.
(..) I brought Charlie Deen, the galloping machine. Oh, man! Figures. I got it in second grade. This I brought too. I brought another candle, but it's nicer than the others. That one's my favorite. I haven't decided what I wanna do with this one yet. Why don't you leave it like that? (..)1996 Foxfire
