I think I have the name I want, though there is a tiny bit of doubt there as one other name is really nice too, but it was the name of one of my characters from a story I wrote.
note, the name isn't Hikari, though that is a fine name too, which means "light" in Japanese. I am not Asian though so I am only looking at traditionally western names.
If it is able to do without much work I intend to changing my last name too, to gain a bit of distance between me and my family, I have never been close to them. The last name I picked is also a normal last name and starts with the same letter as my current one, just in case I can't change it in my state easily, I won't throw the initials off.
