If you mean the green power light, perhaps the yellow/red standby light blew out? If you're referring to the blue light in the disc tray, you can turn this off and on in your Wii settings. >Wii Settings >second page> WiiConnect24 >Slot Illumination Bright, Dim or Off
If you mean the Thunder Stone, go to the New Mauville Power Plant.
The yellow light is the WiFi signal, the orange is the console Charging and the blue/red light is how much battery is being used
It depends on what you mean. If the light is flashing yellow with green in between it just means that your A/V (video cable) isn't connected properly. So just check and see if the cable is connected or not. If the Xbox is just plain yellow then it means it is overheating and you should shut it off. Now if it was red that means there is a hardware failure and you would need to get it fixed. So be glad it's just yellow. :) Hope this helped you.
it means that the power to it is on
it means how much battery power it has
low power light, may be a vac leak
Yellow porch lights are bug lights. By bug light I mean they are not supposed to attract bugs as bad as regular light bulbs.
The wiiconnect24 is on.
The yellow *traffic* light means to slow down and get ready to stop because it is about to turn to the red light.

Without know what the warning light say's, all I can tell you in Yellow means caution.
A yellow traffic light means to slow down or stop completely. When the light is yellow it is about to change to red in a few seconds. Contrary to popular belief by many drivers yellow does not mean speed up.
nice video on the yellow light hope it helps. http://www.youtube.com/watch?v=zn89z_VUcP0
Proceed with caution.
Check your tires!
