To understand the meaning, consider these possibilities:
* A play on words: "Honest" implies reliability and trustworthiness, while "lighter" is a device used to start a fire. This could be a sarcastic comment about a lighter that doesn't work well, implying it's not "honest" about its ability to provide a flame.
* A metaphor: The phrase might be used to describe something that appears reliable but is ultimately unreliable or deceptive. For example, a politician might be called an "honest lighter" if they promise a lot but deliver little.
* A joke: The phrase might be used in a joke or humorous context, playing on the expectation of a reliable lighter.
Without more context, it's impossible to definitively say what "HONEST Lighter" means.
