What is the Number for car lighter fuse?

The fuse number for a car lighter can vary depending on the vehicle's make and model. Typically, it is often a 15A or 20A fuse, but it is best to consult the owner's manual or the fuse box diagram for the specific fuse number and rating for your particular car. If the manual is unavailable, you can usually find this information on a label inside the fuse box cover.
