You might want to try what I did for my former '99 Tacoma. I called the local junk yards and salvaged the bulbs and housing from a wrecked Tacoma. I had it in my mind that I wanted all my lights to be blue and screwed some things up.
Considering the '99s have been on the road for a few years now there should be an ample supply. I know in Austin there was...I even got a new fender flair from where a neighbor rubbed fenders with me.
