If the glider's wing contacts a runway light or deflector at "landing
speed" you should direct your budget at pilot training.

I think the concern is that last few knots with a cross wind and no more
rudder or aileron authority. But then the brake should be sufficient by
that time.

My club recently had its first wingtip damage from a runway light. These lights stick up about a foot or so and are sometimes hard to avoid.

What solutions have other soaring clubs found to deal with them?

I was thinking that it maybe a good idea to put a deflector in front of the lights. If the wing is going to hit, it would hopefully deflect the wing up and over the light.
I was hoping the right design might not obscure the light any more than a tall weed. What are chances of getting something like this approved or accepted by either an airport authority or the FAA?
Did you calculate the loads on the glider-wing/deflector as the glider strikes the angle of the deflector at landing speeds and considering the roll inertia of the glider? My gut-feel tells me that the angle needs to be much shallower.

From a guy with a self leveling glider. We teach about this issue constantly, mostly because we fly in a very space restricted facility with respect to width.
I suspect others have the same issue.
