What amp fuse would I use for an outside light?

The appropriate amp fuse for an outside light typically depends on the wattage of the light fixture and the voltage of the circuit. For most standard outdoor lights, a 15-amp fuse is commonly used for 120-volt circuits. However, if the light is low wattage or LED, a lower amp fuse, such as 10 amps, might suffice. Always refer to the manufacturer's specifications and local electrical codes for the best guidance.
