But also remember that the resistance of the bulb increases as it heats up. When cold, it's *much* lower and the switch on current pulse much greater, which is why you usually see a 15A fuse for a 5A lighting load.
The fuse (as was pointed out above) is to protect the cable, and will generally hold its rated current forever, so the cable has to hold that current safely, too.
