I got these weird little lights for Christmas and no one seems to know what their function is. They’re real bare bones LED lights with a magnet on one end held together by black tape. When i say black tape I don’t mean electrical tape. It’s glossy paper tape that tears easily. I have no idea what you would use these things for because once you turn them on they are just on till you replace the tap or they run out of charge. If they turn on at all that is. At some point I’m going to re purpose them into something more useful. I’m going to need a soldering iron though. Just a cheap one to wire them on to a switch or something. I think they would make good emergency lights with a little tinkering, or mood lighting for toy displays perhaps. The red ones look cool when you use them to light up Decepticons.
