I believe red "anti-collision" markings on the wingtips and nose were
at one time required in Germany (that's why out G-103 has them), but
the requirement was later rescinded.

There was a very thought-provoking study done in 2002 by Dr. Tony Head
of the Human Factors Group, School of Engineering, College of
Aeronautics, Cranfield University in the UK on "Glider conspicuity
trials hald at RAF Bicester in June and October, 2002" - you can
download a copy from http://www.dg-flugzeugbau.de/Data/gl...uity-study.pdf

Long story short: Many "anticollision" markings are worse than
useless, but high reflectivity foils on control sufraces are pretty
good.
