Yes, the fuse is overheating and melting, protecting the electrical system. Probably the fuse and circuit is not rated for the load of the spotlights. I don't know what the draw if the spotlights is, but I think you'd be well off to use a relay controlled, fused auxiliary circuit. Don't put a fuse in that has a higher rating than was originally installed or you'll melt your wiring.
