Well.. the metal clip on my Dectane headlights is fairly easy to close once you understand the mechanism, and I am almost certain it closes in the same way as yours does, MUCH easier than the stock headlights.
If you want to make sure it's closed properly, just get a small mirror or something so that you can see and try it. I can do it blindfolded now but it took me about five minutes to figure it out the first time. The high beam's metal clip is much more tricky, though.
