That's where 5050 LED strip lights came to the rescue.
Step 1: SMD LED strips
As you can see in the pictures the LEDs come with a self adhesive backing. Most do.
I choose the non-waterproof variety because I installed these on top of my kitchen cabinets. Underneath I would have used waterproof. Waterproof can be used anywhere, inside or out, and would make great walkway lighting or accent lighting on decks or houses. Being 12v you can also make some crazy light effects for cars.
If you want multiple colors you can purchase the RGB strips. They will have special power supplies and most have remotes. these can be set to a wide variety of colors and there are even programs in the controllers that will make them fade from color to color and flash and do all sorts of things to give you headaches or trigger seizures.
