When I was at the Sabre factory, they had all of the clearance and side market lights lit up on the campers in the production line. This was something that I have seen at campgrounds and thought there was some utility to it. The trick is that you bridge the two “top” pins (technically #3 and #4) on the 7-way connector.
There are varying schools of thoughts for camp ranging from the extreme of minimal lighting to the extreme of maximum lighting on all night. On forums, you’d be amazed that this can be hotly debated. Before you get your hackles up, remember that we all have our own experiences:
“I know there are some light haters out there. My campsite is lit up at night while eating due to the dear girlfriend’s vision issues. I rather have extra light than her getting hurt. Just remember, there are others who cannot see as well as you do.”
You have to find the happy medium for you and what seems appropriate for the campground around you. For me, I try to have lights out at dark and that includes going up to pull the fuse from the pin.
