I honestly thought that light reflects off of ice (if not, shines through it) but doesn't do any exact damage to it, so it'd be either "not very effective" or it wouldn't have any effect on ice at all.
On a separate note though, I see Fairy and Ice being neutral to each other, for some reason. Maybe that's just me, though. If Fairies were to be weak to ice because they could freeze, by that logic, they should be weak to fire as well, since they could burn, and then they should be weak to water as well, because theoretically they could drown, etc etc.
Too many typing inconsistencies, really. .__.;
