I'm having a blast playing around with these LED strip lights. They have 100 to 300 little LEDs on a flexible circuit board (tape) that has 3M sticky tape on the back. You can stick it to anything. each end has connector wires (one side has a plug). Just hook it up to 12volts (I used a dimmer switch) and it really looks cool. Theye are actually fairly cheap and can be cut to size with a pair of scissors. Since there are connector wires on both ends, both halves can be used after you cut it.
I put them above our slide outs as noted above but could be used under counters or in closets etc. They give off virtually no heat.
I also bought some multi color strip lights...which I have no idea what I'm going to do with them but it's fun playing with them! There is a remote controller you can get for them that costs $9.00.
