Noticed many of the Lexus and BMW round here have the brake light fault. even checked one to see if they were auto and were using the left foot on the brake, it was a manual.
there seems to be a pandemic of one headlighted cars round these parts. every 5th-ish car has at least 1 bulb out.
if the local plod wanted to make some money they could just do a road block/check on any busy road with a fixed penalty fine for driving an unroadworthy vehicle. they'd pay for everything in a single day of checks! much more road safety focused than speed cameras.
I see a lot of those one eye'd monsters too. It's a pretty scary thought to see them going along at 70mph, when their one headlight could fail at any moment.
