Dan,

The landing lights work well.  I don't think they cause any heating problem
because I don't seem to have a heating problem.  The lights are made by PIAA
and I get mine at a website for Next Collection.  As for the longevity, it
took a bit ( and a few bulbs) to get the mounting right.  Since that time I
believe the last set of bulbs have about 200 hours on them.  I'm happy.

If you decide to try them, let me know and I will get the part numbers for
you.

Thanks for the compliments.
