Those look great but the price is still out of line.
I have the 100W Halogen's (not HID's) in my Duckworth leading edges and am very pleased with them. Something like $3.95 from Pep-Boys when they burn out.
One of these days I will upgrade to LED's but not until the price comes down.
PS. The other thing I did was to aim the left one down so it lights up the taxiway with the tail down and the right one is parallel to the wing. That way I can taxi out with the left one on and the right off. Once I take the runway, they both come on. It works great and on final the combination will illuminate the runway at 500' AGL.
I wish we lived close by so we could compare them side-by-side.
