Yehudi lights are to make a dark airplane blend into bright sky. A glider is not very dark. I certainly have no ownership in strobes, while not a cheap option, I have had enough close calls and one paint scrape, that I have a Flarm, Mode-S, strobe and 20-15 vision. If you hit me I will be ****ed! While I have not seen a strobe equipped glider, except for one N4DM that had a strobe mounted on turtle deck, I could certainly see that flash, but I could see the 26.5 meter wings too. I do know that anything unusual can get your attention, like a glint of reflection, a strobe, a maneuver etc. It is hardly worth debating the merits without empirical data and test assumptions. I merely posted the video. On ground if I turn on my strobe in very bright light it really shows well and as I said others say it is bright, have o idea if they see the strobe or glider first. I do know added high visibility devices does not hurt your visibility.

My Google Fu is strong today. I found a Wiki page about the use of counter-illumination for camouflage that was quite interesting to read.

From what I'm reading, the brightness of the strobes could work against you as counter-illumination if they are not significantly brighter than the surrounding sky. On a bright, blue sky day, would a bright strobe strip help or hurt your visibility. As I said in my previous post...counter-intuitive...
