Unless factory equipped, HIDs are illegal. At least in PA, won't pass state inspection either.
A number of years ago, the big deal were those blue tinted headlights. My local auto parts shop sold tons of them, so I put a set in my Bronco. I got pulled over by some Cop that had nothing else to do on Memorial Day weekend. I got a warning. Something about the color of lights facing forward on the car.
If you like the car, get it and swap out to factory lamps if you;re concerned.
