We put a 55 W automotive head lamp in each wingtip, one set for 50 feet in
front of our 601HD, the other for 100 feet, shining through a curved
polycarbonate rectangle (with rounded corners) in the leading edge.
First, they were a LOT OF WORK to make (certainly more than 50 hours); the
spring-loaded mechanism to adjust their angle was complicated, as was the
holder to have the polycarbonate conform tightly to the leading edge
curve. They have individual switches. Two things on their use. A 25,000
hour airline pilot friend (who also built a 601HD) insists that one of the
lamps be on whenever we fly in the daytime. He says that birds see them.
I'm almost certain I heard Chris Heintz make the same comment some years
ago. Certainly the light is very visible from the ground. From the
aircraft seats, you wouldn't know the light was on. BUT, the other day,
for the first time, we arrived back at our home airport rather late; it
was not dark, but getting so. It was great (and helpful) to see two discs
of light roughly 50 feet and 100 feet ahead of the aircraft on the runway!
