I got my LED strip lights on Amazon. You can get a 15 meter strip of any color or multi color for under 20 bucks. I went with the SUPERNIGHT brand
There's literally thousands to choose from.
You can cut them to any length you need providing you know how to solder, or they make clips that will make the electrical connections.
You'll most likely want to make sure you get water proof strips.
The RGB strips you can select any color you want either by hard wiring a single color of getting a controller with a wireless remote to change.
They even have controllers that will alter the lights to sound.
May the Lord bless you and keep you.
May the Lord show you his kindness and have mercy on you.
May the Lord watch over you and give you peace.
Numbers 6:24-26 (CSB)
