To me it would seem easier if these 808 manufactures would do something like this. At the LED end of the 808, instead of adding a colored LED, just put an ultrabright white LED and then make different color end caps with some kind of reflective material in the plastic to make it brighter, then just sell different color end caps. Then you could change the LED color on any battery to fit your mood by just popping out the plastic cap and putting a new color in. Or maybe embed the colored LED's into the plastic cap and when you put them in they make a connection to the internal battery circuit.
