3rd brake light bulb swap

Sadly I don't have a manual for my car so I was wondering if someone can help me determine the model/bulb # for the 3rd brake light in the rear window. 98 LS

Do what I do and take the bulb out of the brake light and then goto autozone or your local autoparts store and compare the light with the ones there..

That's normally what I would do but I'm ordering some special LED's and that bulb is one of many, I was hoping someone happened to know the bulb number.
Thanks for the reply though :)
