I put these on the back of my tv for mood lighting and the double stick tape sticks nicely.  They can also be hung on the wall with little clips.  This strip plugs into a USB and has a button to change the colors of the lights or they will keep changing colors on their own every few seconds.  They can be controlled with an ap on your phone also to give you more color options.. ( they advertise a million different  combinations)  I could not get the ap to work right on "my phone" but it could just be my older android phone (my reason for lower rating).  But they do look nice!
