I suspect that the nearby street lamp will be enough to deem it 'lit'.

I am concerned that the roaming vandals we get around here some nights, will set it in motion and it will roll into my car.
The caravan will not be insured.

I could park elsewhere but like to have my car in view when I hear passing groups of yobs --which I suppose he has done, rather than put it in the parking area at the end of the culdesac, where no one can see it.

I will wait and see whether the binwagon gets past it easily on Tuesday and the school swim bus gets past OK on Wednesday.
I suspect that another neighbour who has it in full view on the ground floor may report it to the highways dept.

This neighbour used to live in a caravan with the gyppos, so we are a liitle more concerned than most about what might happen next.
