The FAR actually says "approved" lights. Most interpret that to mean a light that meets the FAA's specifications (brightness, angular coverage, color, etc) but not necessarily TSO'd. It is clear that Christmas tree bulbs are not "approved"!
This is for nav and anti-collision lighting. There is no requirement for landing lights, at all. You do not even need to have them, if you so choose.
