Sorry to hear about this, I have helped several neighbors where either the neighbor or their landscape company cut the wiring with a string trimmer or edge trimmer. These breaks can usually be repaired with a crimp splice, but in areas where the wiring could be subject to future cutting, I typically install a piece of 1/2 inch PVC pipe to protect the wire. Also, if the pond light is an LED type, there make not be a "bulb" to replace, and the entire unit may need to be replaced. In this case the lead wire needs to be long enough to extend completely out of the pond, so the splice will be made outside of the water.
