You can fix this to some extent by unchecking the 'Clip final shaded color' in
the Render Globals.

I've just tried this, and, sadly, it doesn't seem to do the trick. With the
semi-transparent material in front of the camera, (which I've named
"sunglasses" BTW) any white "overexposed" light source becomes grey no
matter what the incandescence level of the "lights" material. Perhaps the
"white" of the material is only computed in 256 grey values, and the
"sunglasses" bring THAT level down, not the huge incandesence level that I
added to the material.
