If you’re ever in a car and your lighter goes out, there are a few things you can do to take it off. If you’re using a cigarette lighter that has an on/off switch, turn it off first by pressing the button. If you’re using a lighter with a key ring connector, remove the key ring from the connector and unscrew the light bulb. If you’re using an old-fashioned lightbulb, unscrew the neck and pull out the light bulb.
