I saw them on QVC the other day and they look pretty cool. They project laser lights on your house, trees, bushes, etc to look like Christmas lights. I was wondering if anyone else has used these. I am lazy about putting lights up and this seems like it would look pretty neat. I do have a street light in front of my house, so I was wondering if it would affect how they look on my house because the street light makes the front of my house pretty bright.
