Yes there are those who get in and drive off on their DRL LED'S at night so not having any rear lights on.
The one I saw earlier despite the lights on this pre DRL car being off (the street lights and other cars were making the dummy more obvious from their lights) really took it to another level.
As in outside lights at night off!
Interior light on while driving about at 30mph!
Well done to this founder member of DENSA!
At least we know what you look like.
