The second pic looks like a waste transfer station - in which case having the beacons on is probably mandatory as well as being a good idea anyway with half asleep shovel drivers trundling round in the dark!

Aye fair enough if you're driving about on a site but imo not much point if the van's stopped. Personally if it was me I'd save the battery/diesel and switch them off. In a dark place like that with 6(?) halogen rotators on the go there's a chance the drivers will be blinded and not see the real danger - you disapearing under the bumper
Anyway I was looking through your photobucket, nice van RSP
