1) If you have a bulb that starts an arc (shorts) when it fails a 3 amp fuse rather than a 13 amp one can be the difference between the fuse just blowing and the bulb exploding. It's rare but I've seen it happen.

2) A lower current fuse means less chance of a fire if any weird over current fault develops.
