It says they are for off road and show. They are not DOT approved. That means that they are not legal in PA. With that being said, I doubt anyone would notice until you went to get them aligned. The European light pattern is very different than the US / DOT light pattern. I prefer the European light pattern.
I am a Certified PA inspection mechanic. I would not have a problem inspecting a vehicle with them on. Other mechanics may have a different opinion if they follow the exact letter of the law.
