Love these lights! Took my husband a weekend to install but was well worth the time. We used two-sided tape to help secure and then screwed them in. We have 2 sets with the max length you can have. We have a small portion with no lights but it’s literally the length of an area that doesn’t have a light and is where you can’t see so it’s not a big deal. I set them on timers within app and hooked up to my Alexa as well! We love them and no more hanging lights every year!!!
