I'd be making an image file with those bits that are meant to glow in the image, and with the rest black. I'd material group the mesh so that those bits corresponding to "glowing points" used that image. Then, just set the ambient_value to > 1 (diffuse_value to 0) and your lights will glow and emit light if that value is set high enough.
