Whenever my speakers are on, this tiny yellow light comes on.  It kind of clashes with everything else now since the blue theme took affect.  Let's change this one too:

   I got a nice 4 speaker setup from Altec Langsing, the ACS54.  There's a yellow LED in between the surround sound knob and the master volume knob.  We're going to replace that today with the blue variety.

   This will be slightly different than before.  You may notice that the LED hole is extremely small.  We will either have to enlarge the hole or shrink the LED.  I decided to shrink the LEDs size instead of enlarging the hole.  To do this, grab yourself some sand paper.

   I took the 5mm LED I had and worked on it across my 150grit sand paper.  After a good 5 minutes of filing it down, it fit into the small hole.  Before anyone asks, the bulb is made of plastic, its safe to file it down a bit as long as you don't hit the metal.

   I flipped the speaker around and removed the screws to reveal the PCB.  Took that out and repeated the steps described before.  Installed the unit back into one piece and fired it up again.

   Even though the LED was sanded, it still produced a blue glow brighter than what I had before.
