Back in the '50s law started requiring ID and clearance lights on trucks and trailers. The idea was the amber lights above headlights, or the extra red lights, would let motorist know the vehicle was larger, (And likely slower uphill) than normal. And it was thought that by spacing the ID lights you could judge how far away the truck is. This century they are only used as a reason to write tickets.
Back before all the daytime driving lights, and all the improvements in headlights, I could tell how far from a car I was by the brightness of the lights.
When the law declared I could no longer delete the turn lamps from my MC, I argued that until they where made self-canceling, electric turn-signals should be illegal. Nobody is to stupid to pull their arm in.
Maybe the best idea would be stop the ones without lights, hold them for a few days for mental health evaluation. Why are you trying suicide?
