I wonder if/when they will stop the various sizes of automotive bulbs(from headlight/tail/dash bulbs from being made/imported/sold? I know retrofits are common, I have my tail/park lights changed already and will probably change headlights when the next one fails - if the car remains? I wonder if a fat tax will give the image of choice and achieve something similar?
