what are the lights for on the bottom of the outside mirrors and when do they come on?

Those are "puddle lights" and from what I've seen they come on when you unlock the car.

If you have the smart key system, they also come on when you get close to the car. I have to basically be right next to the car standing in any puddles they might illuminate before they actually come on if I don't use the fob to unlock the car.

Ha ha. Same thing hear I have the smart key and I find it funny that the puddle light come on to ilumenat the puddle that you are standing in. For me not a big issue as we don't get mutch rain hear. So I am fine.
Look at it from another point, back then it was an innovation. Top end cares did not have the things that Lexus had.
