A fuse checker particularly adapted for use with miniature, plug-in fuses for testing the fuses while the fuses are in operative position in an electrical circuit. The checker includes a housing from which extend a pair of parallel contact points adapted for engagement with terminal tabs that lie within terminal access openings in a fuse housing. A ground lead is provided for completing the circuit, which includes a pair of light emitting diodes that have their lenses positioned to form part of the surface of a checker housing. A separate, current limiting resistor is applied between a respective LED and one of the contact points and the ground lead. The checker housing can be a hollow structure or it can be solid, to fully encapsulate the circuit elements that are positioned within the housing.
