Going off tack a bit (yeah, I know, what's new). My eyes and brain does NOT like the multifunction lights used on modern vehicles. Cars, bikes, and buses. Don't notice it as much on Heavy Haulage (as they are obliged to have extra lights and reflectors). And I do not like sequential led indicators as now being pushed on Audis etc. They are simply NOT as visible under normal driving conditions.
This is a realisation that has struck me this month here as we are having un-customary constant rain. So lot's of spray and road reflections. I am loathed to remake parts for the R3. But certainly has made me think how BEST to do it if I do.
