There are about 20 small lights throughout the campground to help guests get around safely at night. Each had a small 7 watt bulb that stays on whenever power to each of the campsites is on, so essentially 24 hours a day during the camping season. Ideally, each of the lights would have a sensor to turn them on only at night. This is the eventual goal, but an easy solution in the meantime was to replace all 20 7 watt lightbulbs with LED lights that use about 1/2 watt each. The LED bulbs we got are direct screw in replacements for the old incandescent bulbs. We decided to get blue lights to give a distinctive look to the campground at night.
