That's the whole point, though... The logical endgame here is to NOT allow you to change your headlamp bulb, and require you to bring it into the shop so that an authorized, qualified technician will replace it properly, thus maintaining the integrity and safety of the automobile.
Logic is not necessarily at play here. They are again going after the aftermarket and home mechanics. If you are not an "authorized" aftermarket manufacturer, who has paid the fee to get the "authorized" label, you will have no business, UNDER THE LAW! This is just like a Microsoft EULA: you pays the price, but you don't really own the device. It's still under the control and maintenance of the manufacturer, and you won't have the right to do any maintenance. Taken to the extreme, there won't be a way to even open the hood unless you have the special tool to open it. And selling the tool to any unauthorized people will be made illegal. Have a flat? You better have paid up your AAA, or you're stranded.
This is a very slippery slope that the law is considering. I hope this is completely and totally quashed. Or at least limited to a voided warranty.
And, there are LOTS of vehicles with LED elements in their headlamps now. They aren't necessarily the headlamp bulb itself, but rather secondary marking lamps. I think that's what A/C was talking about. Hopefully they don't come out with a law that states that they have to be fully functional, OR ELSE a ticket.
