- bluGill 6y agoNot the oldest still functioning light. But the oldest in normal use - there are older bulbs in museums that are turned on for special occasions (by experts doing their best to ensure it won't burn out). This bulb is installed and used as a bulb. (though mostly it is there as a historical element - modern bulbs produce more light and would have replaced it if there wasn't a historical reason to keep it around)
