I know that in Japan the drivers actually turn off the headlamps and activate the parking lamps even when stopped at a stop light, and it seems that I recall the same practice in Singapore and other ports beyond. I never asked if it was the law or perhaps they were doing it to save fuel. If I was to do that with my '41 I would more than likely be crushed by now, especially down here in Florida where a lot of drivers don't see well, especially at night.
BTW, Randy Rundle, AKA "The Electrocutioner" has a tech tip at
Make your parking lights into running lights
