VA and glSecondaryColor3fvEXT

I have implented per pixel lighting as shown on Ron Frazier’s site

Now I would like to render the whole thing with vertex arrays. I have a code snippet which deals with multitexturing and vertex arrays, but I have no idea how I shall use the glSecondaryColor3fvEXT. If anyone knows how to do this I would appreciate to learn from him. Thanks for the help!

use glSecondaryColorPointerEXT() to point to your array.
