ABSTRACT:
An automobile fuse with damage indicator, in which two conductors of a small indicator bulb are connected in parallel with two conductors of a fusible link so that the bulb does not light as long as the fuse is in good condition; but will light immediately by current passing through the load after the fusible link is broken by an overload. The lighting of an indicator at the place where the fuse is installed directly indicates a burnt fuse, particularly at night or in a dark place and trouble shooting and replacement of fuse can be conducted quickly.
