Fuse cards are small devices used to protect electrical circuits from damage caused by excessive current flow. They are typically made of a thin piece of metal that melts and breaks the circuit if the current flow exceeds a certain level. Fuse cards are used in a variety of electrical devices, including cigarette lighters, radios, and power windows.

If the fuse card in your cigarette lighter blows, you will need to replace it with a new one of the same amperage rating. You can find fuse cards at most auto parts stores.
