Real easy. I changed mine while I had the back cover off to paint it black.
It's a little peanut bulb, go to a car parts store and get a "194" bulb. You can even get it in red or blue if you want to change the color, but it will be dimmer.

Used to be Red, now it's Green. Open for name suggestions.
Yep, easy, but in my case, as soon as I touched the bulb housing, the thing came on. I don't know what the deal is, maybe needs bulb replaced anyway, but at that time the bike only had about 7800 miles.
ok, that is a great help, thanks pvster and brew crew, i went with the bling blue. Cheaper off ebay than the local shops, and i dont have to leave the house.
Beware, the blue is hard on the eyes at night. I ended up swapping them out for a different color after a week of straining my eyes to read the gauges. I would advise you to order another color for back up.
