I'm going to install a Whelen 600 wingtip light this weekend -- that's the
one which includes the red/green position light in the front, a strobe in the
middle, and a white light at the back end.  My question is simply "where
exactly do I locate it?"

I'm familiar with the FAR's, at least with the drawing in the Aircraft Spruce
catalog showing that the strobes must both be visible from 1200 feet behind
the aircraft.

The wingtip is slanted so that the wingspan is narrower at the front than at
the rear.  Presumably I should slide the lighting unit aft until the strobe
is not fully obscured by the aft edge of the wingtip?  Or should I just put
it halfway between the leading edge and the trailing edge and say "that's
close enough?"

Has anyone had an FAA inspector look closely at the wingtips and verify that
the lights are visible 1/4 mile behind the aircraft?

By the way, I should probably apologize to the folks at Lancair whose names
I've (silently) taken in vain when contemplating installing "those crappy
wingtips".  They really are turning out very nicely!  They really stiffen up
when they are installed, and I have high confidence that mine will turn out
as nice as all the finished ones I've seen at the airshows.
