I have recently tripped over a concrete block placed to stop the car
going back too far in the parking lot (and was injured), and thus I
would like to suggest that appropriate precaution against accidents
be considered in setting the lighting level.
After I was injured I remebered that I had a near accident in a
hospital parking lot under similar situation during night when I
drove my colleague to an emergency room of a hospital.
