What is the preferred way to waterproof/seal a hole through stucco for the purposes of mounting lighting and the like?

I need to mount some things (for example, lights) on our stucco-clad house. I know that the waterproofing is done by the housewrap underneath (tar paper in this case), so I'm worried about the water collecting on the upper surface of the light, wicking down through the stucco, and then riding that convenient cable through the moisture envelope.
Is simply "caulking the heck out of it" the right way to do it? If so, should I be using like an elastomeric sealant? I'm used to considering caulking as a band-aid that should be remedied by proper flashing. Or, is there just no "right" way to penetrate the wall and something like ugly surface mount conduit is safest?
