Put up the first of the decor for Christmas earlier, outdoor ones but found that I need to replace two of those lights because, one has stopped working and there is rust in the battery box even thou the box has a rubber seal to surpposely keep water out, the other, two of the lights are failing on a string of five, so I need to go hunting for replacements before work or during my break, if there's nothing there, I'll likely order from the web, the remaining lights which are all similar desgin, I have placed the battery boxes inside of plastic food bags as a means to keep the weather at bay
