I think I've tracked down the problem..
If I tighten the metal disk too much, the light takes several clicks to activate, but if I loosen it just a tad then it only takes one click. The issue is it tends to loosen up too much over time because it's not torqued down.
One more thing I totally forgot that I did was to pull on the spring a bit to stretch it out. Hope this helps also.
