The light is designed to tell you when you have a new msg, so it either pulses on and off slowly or stays permenent (You can choose this in the Wii settings) when an unopened msg is on you're console.
T
o get the light to stay on just get a friend to send you a message and don't open it! Or send one to yourself via an E-mail.

Then you can enjpoy the Ultra-Cool blue light all the time :p
But you'll never know when you get a new message without checking each day...
