> Sure, if your requirement is that you pass regulatory muster, then lighting is "simple" in that you can buy an off the shelf bulb, socket, and housing. But those aren't the requirements.

Yes they are. You don't get to point to random fancy things and call them "requirements".

> A phone light is just a little LED you could buy for a dollar and put on your keychain.

You're taking "phones have lights" too seriously. It was a deliberately vague and useless rebuttal to a deliberately vague and useless point. The real answer is what I already said. Replicating the functionality of a bulb/socket/housing is not hard to such an extent that the only reason to bring up lights is for jokes. So the joke got a joke back.
