Toyota used the same gauge of wire for the 9005/9006 harnesses...I think it's 55 versus 65 watts, not that much overage. I ran that way for several tens of thousands of miles without issue. You do go through bulbs a little bit quicker as the 9005s aren't rated for as much life, but it's a lot cheaper than going for some froufrou bulbs. Hell, you can get away with 9011 HIRs in the lowbeam sockets, but for the money, 9005s are the best shine for the buck.
