I think we, collectively, are in that awkward time period between "dated" and "classic" and I would gather the OP is fighting the "dated" and trying to "freshen" the look (which I can understand). Personally I have never fallen into that trap because anything "new" will become "dated" and if updated, it just starts the cycle again. Classic just stays classic.
I suppose it's the same with clothing fashions...in future photographs, anything trendy now will look dated, whereas anything classic will look the same...dull, but not dumb. Personally I've been wearing Top-Siders, khakis and white shirts since the 80's and if it wasn't for my hair, it's hard to tell when a pic was taken. Dull? Maybe. I just call it classic...or perhaps as a child I was just overly influenced by the Professor on Gilligan's Island.
Anyway, update headlights if you wish, but remember that 20 years in the future 718 owners will be lamenting over how dated their headlights look. At least by then (hopefully) the 986 lights will look classic....and yes, maybe then amber will be the new white.
Back to the OP...at least your having fun. What else really matters?
