You basically get a 5 metre length of led's on a roll a little remote control and connector and a mains adaptor. I added a 12v cigarette lighter type plug from elsewhere for about another £2.50.
I have located the led's hidden under the lip of the pop top facing in and protected from the weather although they are supposedly water proof. They come with a self adhesive backing which isn't really man enough for the job as the inner surface is too rough so the addition of a smear of Evostick (other instant grab adhesives are available!) was called for.
As the leds are longer than actually needed you can cut then to length.
The ends and the controller were secured using some velcro sticky pads so they can be removed.
the lights were then plugged into a multi socket that I have located behind the wardrobe top taking a power feed from the kitchen light so it is all hidden
The cable just feeds through the pop top opening. The controller allows several different effects.
Example below!
So not a tricky job, possibly a bit tacky but who cares!
