I don't have any experience doing this but I have seen some really good examples. The best ones that I have seen are virtually invisible during they day. They are very low profile but really make the house pop at night. Do it!
This seems like the right idea. You don’t want it to be noticeable until it’s on at night.
I can do the installation of the lights and do a clean enough job. It's the controllers and programs that make me think twice, though I have been reading there are controllers that are easy to set up and use. It's gonna be fun.
