^maybe. i don't know though... that can't be good for the battery especially with power hungry filament bulbs. also things like trees, trash cans dont have lights. i'd rather alert someone to my body getting out of the car vs the car just sitting there. that's what insurance is for.
Dusty old British laws that no one really obeys anymore.
The bulbs would run at very low voltage and the dash lights obviously don’t come on either, which saves a little power.
