Blue Interior Lights

My friends has a 2003 Grand Am GT. He wants the interior to be blue. I need some help on where to find these blue bulbs that would replace the factory ones (like the dome lights and reading lamps) and what the size or part number they are. We tried going to Autozone and buy them blue caps that go over the bulb but them things started to smoke so we quit that idea. Any help would be great.

Most of the interior lights are type 194

Cool. Now the next problem is, where can i find some blue light bulbs?

You can find bulbs at your local autozone. They seem to cary a wide selection of colored bulbs. Just picked up some red ones for my car the other day.
