There are really four ways to go about this.
Buy a repaired unit online (eBay). It can be a bit pricey, but it's lot cheaper than a new one from the dealer. Some of them even come with an integrated auxiliary support, and they're much faster to replace. You also get a working LCD, in case yours is broken, like mine.
Pay a repair shop to do it for you. One such shop is http://factoryradioservice.com/
The repairs can be a lot cheaper than buying a complete unit, but you do have to ship out your radio to them, which can be a real inconvenience if you need to drive the vehicle in the mean time.
Disassemble the radio and replace the light bulbs yourself. This is the cheapest solution, but also the most complicated one. You need to be pretty handy to get this done, and have enough spare time to pull it off. A soldering iron and some patience is required for this job.
Buy the replacement parts from Pioneer's website. This may end up being more expensive than buying a repaired radio online, but there are still a few plus sides to this method. One is that you get to keep your original radio, and two, the repair is a matter of removing a few screws and putting the new part in.

In this tutorial, I will be going over the third option. I will not be covering the removal of the radio, since there is already a thread about it.
In case your climate control bulbs
are out as well, there is a thread for that too.
I will say this though, I found a great SST (Special Service Tool) for removing the A/C vents and the bottom trim piece. It's a Rubbermaid plastic spatula. It fits perfectly into the tight crevices and doesn't scratch the radio. Looks like this.
Now for the radio button lights, you will need to order them from http://www.mcmelectronics.com/
The part number is 25-995
. Each one costs only $0.41, so I suggest that you replace all of them at once. You need 12, but I recommend buying a little more in case you mess up. I bought about 20, just to be safe.
They're not a perfect match in terms of dimensions, but they fit just fine. The original bulb is a little bit shorter. Here's a good side by side comparison. (the old is on the right).
Now for the repair.
Remove the circuit board from the radio.
Unsolder each little light bulb with their plastic holders.
The green caps will be transferred to the new bulbs, later in the process.
You will end up with something like this. I used some tape to hold the volume control **** from flapping around.
Old bulbs. 11 out of 12 (I did one as a test run, before doing all the other ones)
Remove the old bulbs from the plastic holders
Insert the new bulbs into place and bend the leads.
Don't they just look so happy?
Trim the ends to size and bend them into place, just like the factory bulbs.
Having something sharp, like a box cutter, helps tuck the wires into place.
Bulbs are ready to go back
Resolder the new bulbs back onto the circuit board.
Add some extra solder if you feel like the bulb is not sturdy enough.
Replace the green caps
They won't be as flush as the original, but should still hold.
They make me think of PacMan
(the LCD back light broke when I replaced the climate control bulbs)

Hope this helps anyone in need.
Let me know if you have any questions, I will be happy to answer them.
p.s.: Thanks to sphillips
for providing me with the information on where to get the replacement bulbs.
