On our recent trip to Death Valley and Valley of Fire, we experienced some ghostly lighting effects. When we turned off the ceiling LED lights in our Northern Lite hard side camper, several LED cards continued glowing softly. The switch had no effect. After several days, it resolved in both lights that had the issue.
I spoke with NL this morning, and they said it was because of too much moisture in the camper. Two good sized humans and two good sized dogs put out a lot of respiratory moisture. Apparently, in a high humidity situation, the switches allow a small amount of current flow. The recommendations were to have much better ventilation at night, plus keep the heat up. They recommended 70ยบ F, with is way warmer than I would like, but if it works...
So, if you have "Ghost Lights", try more ventilation and heat.
