We never plug it in, so it just sits in the garage and takes up space. Uses household light bulbs. All three lights turn on when plugged in, pretty easy to access the bulbs if you would just want one light on. I think you can buy programmers for $30 if you'd want it to change on it's own. Didn't look too hard, but the few I saw like this were going $150+, so I'll put it on here for $120 OBO
