12mm Diffused 5V WS2801 RGB Flat/Square LED Pixels, 50/strand, IP68
LED pixel strings with pre-soldered JST style connectors. Not only are these fully waterproofed, but each LED is also independently addressable, opening up entirely new lighting possibilities. Each LED is powered by an WS2801 IC, and are therefore compatible with a wide array of controllers and open-source code.

Sold by the strand, each strand has 50 pixels in series! Each strand has two JST SM 4-pin connectors so you can connect multiple strands in a row, as many as you wish, just watch for how much current they want.
The WS2801 employs a 2-wire serial data connection, similar to SPI or I2C. ICs are chained together which means whole strings can be controlled using just 2 pins on your microcontroller. For you Arduino users we highly recommend the open-source fastspi library as jumping point for your own code. There is plenty more information available in the datasheet linked to above.
