The lights are working great! One thing that I have
  noticed is that my 65 w bulbs generated enough heat to
  break the glass lense. I would replace yours with a
  tempered one. Check w your local craft glass outlet.
  To reduce heat I also drilled several vent holes in
  the fixture. My lights are on the gear legs and when
  they are up get almost no cooling air. Yours may do
  better up in the breeze.

Randy,

 

I am a bit puzzled about your problems with such a low wattage bulb. Are you using Halogen 12V sealed lamps?  I seem to remember that most 75W lamps or below are usually in a "sealed beam" configuration.  If you are using Lancair leg fixtures (Tim Ong devices) there should be no problem. 

 

I didn't like the low candlepower of 75W lamps so I use a 100W  unsealed projector lamp with a tempered cover glass obtained from Edmund Optical (online).  Being old and forgetful, I didn't like to possibility of leaving the light on whilst the leg was tucked up in the wheel well, possibly causing a fire or softening the wing upper skin. Thus, the leg light is wired so that it cannot be on unless the gear is down and locked.
