"sswift: That's the way it works, there is nothing wrong with it. Self illumination masks out regular light, and so specular highlights are not produced in those areas."
I beg to differ. I have headlights on my car. When I turn them on during the daytime, they are self illuminated, but they will also reflect light from the sun that is much brighter than the lights themselves are normally. Plastic lights on a spaceship also would be expected to reflect specular light. If you don't want them to, then you can easily paint that bit out of the specular map.
