Well, I don't know if these are LED, or just normal rope lights, probably just normal rope light, but I have no clue if they are LED or something ancient. I got them after Halloween a couple years ago. They are actually orange, but when turned on, they turn more red. Great for ambient light. We enjoy just laying them on the ground in different configurations, depending upon where and how we are camped.
They cost about $2.00 each after Halloween a week or so. I bought 6 sets and hook them all together. They are a lot of fun, and the darker it gets, the prettier they get!
It's just something to think about... no attaching to the camper this way.
