It's obviously hard to see a glider that is coming straight at you.

So what about a narrow beam LED strobe aligned with the glide path
vector... would the other glider see it? Would it be legal? Could
you shine it through the canopy with a baffle to block internal
reflections?

Has anyone done this?

I once saw another glider coming towards me on a ridge with wing tip
strobes. It really got my attention and in plenty of time. So I
kinda think that this would work.


Good idea, several solutions exist, partly professional, partly home
made. A few links:

A solution like this can be integrated into the fin (done at
Schleicher), the additional price will be around 1200 EURO. One glider
at our airport is equipped with this, visibility is excellent.

This is much cheaper, and can be attached quite easily to any glider.

There was a discussion in the segelflug.de forum some time ago, this is
a selfmade solution from Wolfgang Schmidt.

If you run this all day in flash mode, you'll probably need an extra
battery.
