Treat it as this month's job, not an emergency, and not a decoration. The indicator going out usually means the device absorbed its rated energy and sacrificed itself, which in Central Florida can happen in a single hard season. Until it is replaced, the panel it guards is unprotected during the most strike dense months in the country. The replacement visit is also the moment to confirm the device class matches the house's loads, especially if a variable speed air handler or new pool automation has been added since the original install.
