Convertible interior light?

Could someone tell me about the interior light(s) for the convertibles?
The only lights mine has are in the instrument cluster. Been using a flashlight for years, but that gets old.
Under the dash, there are a couple of holes on the passenger side that look like it would have been there. The wiring is such a mess, it's no help in figuring it out.
I know the lighting couldn't have been very good from the start. Has anyone tried any kind of custom light setup? I was thinking some kind of lights in the doors or under the dash pad would be good, but don't know which way to go...
Any pictures you could post of the stock lighting or a custom setup would be greatly appreciated! Thanks!
