Hi, Nathan_A_RF,
Thanks for this. I confess I am a bit confused. The entire East Boldre is inside New Forest National Park which is 40 miles an hour zone. There's a zone sign in front of the village with 30mph limit and the Main Road has 30mph road sign repeated throughout. Most of these side roads are not lit, though Chapel Lane is an exception. So I guess it should be all lit streets should 
"nsl_restricted" are non-lit should it be "sign"?
