Turning battery- powered Christmas lights to run off a solar panel? It can be done! In today's video I show you how I built Christmas lights that work with a solar panel and a rechargeable battery. The battery is charged during the day, and when night comes, the lights are automatically turned on and run from the battery, which is then recharged the next day. These lights are perfect for mounting outside where there is no electrical outlet nearby.
