Hi
Been looking at these http://www.hylite.uk.com/decklights.html

How does an LED light change colour? Would each fitting have LED's of each
colour, or do the LED's themselves change colour?

The lights will either contain 3 different LEDs, a red, green and blue,
or they will contain a single multi-colour LED, which contains 3
elements within the same LED package.
