The fuse-holder is non factory. If the wires leads to relay(s) and harness that is plugged into the factory headlight wire harness and headlight bulbs, then it is an after market add on wireharness for the headlights.
At the relays if the wires are good with only the relay(s) melted off, replace the relay(s) and replacing the fuse holder should solve the problem. If the wires are in bad condition, either you can remove it and plug the factory harness back onto the head light bulbs or you would have to do a rewiring/replacement of the wireharness.
Melting of the relay is due to overheating as the headlights would cause the wiring circuit and components to heat up if connections are loose or the capacity is insufficient due to higher wattage bulbs used.
