Europa-List: Monowheel dual sealed beam?

Working on wings, figured should run any and all inside prior to bonding on
top skin.

I liked the idea of mounting a light on each outrigger fairing.

Did a test the other night with a box of lights. Had some 35 , 55 and 100 watt
halogens that would fit, some driving and some fog lights. At best dismal
results. Tried removing reflectors from fog, same thing.

Tested a Cessna sealed beam 100 watt, worked great.

Tested a larger diameter 100 watt sealed beam and that worked even better than
the Cessna style.

Was reading on the aeroelectric list, and someone mentioned that if he had an
Europa, he would use a dual filament sealed beam, and use high for landing and
low for taxi. For approach would wig-wag between the 2.

Has anyone done this on an Europa?

Has anyone mounted a light on the lower cowl with good results? Details
please.

Has anyone mounted a light on the landing gear with good results? Details
please, also can you put on trailer with light?

Do 1 light monowheels work OK for Taxi and Landing?

Thanks

This is post I read.

This is exactly the kind of thing that calls for an experiment rather than
(maybe good and erudite) speculation. I would surmise that the result
depends greatly on the beam angle and direction of the lamps. They are not
identical. When a star twinkles it is more noticeable--this does not depend
on having two stars, or the distance, or anything except the way the brain
processes images.

Easy experiment: Park your Jeep Cherokee at one end of the runway with an
observer with videotape if you can at the other end . Cover one headlight
with floor mat. Signal the beginning of the test with three gun shots.
Alternate between high and low beam.  Signal the end of the test with three
more gun shots. Get the report from your observer review the videotape.
Okay, I was kidding about the gun shots.

If I had an airplane with one single lamp, like a Europa, I would install an
automobile dual-beam headlamp and use the low for taxi and the high-beam for
landing (maybe both on) and wig-wag them on approach. If the aircraft is
equipped with lights at all, then pulsing their intensity will enhance the
aircraft's visibility. Could this be incorrect?

Truth in lending--Since I sell wig-wags, I have a dog in this contest. I
will sell you the world's best wig-wag with no risk. If you don't love it
return it.
