We might not want it, but we'd be better off with something bigger than what we have been getting lately.
LEDs + least weight wins = ever shrinking cycle lights. Tiny, point source-esque lights increase dazzle, decrease visibility and provide far less distance information to observers (i.e., at 200 meters a point source light looks like a point source - and still looks like a point source at 100 meters.)
This is sort of a 'lost knowledge' thing. Here's what's happened to cycle light size in a generation:
