Alright I have some XSPC parts and one of them came with this little blue led, it was the reservoir I believe. Ok so I have watched many people on Youtube unbox their product or whatever and ask "what is this for?" and to be honest whats the deal with this? So I just stick this little blue led into the little notch on my reservoir? That is what its for? I just would like to hear opinions maybe I am just being crazy, but this little led is hilarious. I keep thinking its some kind of XSPC joke or something...opinions?
