That's correct once the key is in the on section they light up all the time.i asked a guy with a '10 XLT directly over on the "other" forum, and he told me that they do in fact light up. from what he said they actually light up with the headlights off or on, kinda like the headlight switch itself, so that's pretty cool! now i just need to find a set that dosin't cost a zillion bucks! lol
