I love these lights. They were super easy to install! We connected them to the USB on our TV. There is adhesive tape to glue them to the device or you can lay them on a surface.. Its perfect because  they go on when the TV is on and off when we turn off the TV. You can also plug them into a plug like you would a charger if you wanted it on without the TV on.  The colors are great, not too bright but not dull at all. We love the purple colors. When you install make sure the remote is in view of the USB plug for best control.   These are great lights and I would totally recommend them!!
