    Must be some type of light sensor.

    Why ? With this kit, its looks like just a chamber like a mini M&M #67 without the float (piped the same way as the 67) and it's just a probe type LWCO. First item below "Cast Iron Hub Assembly" Has nothing to do with the sight glass except it is a convenient place to put it like the 67.

    I think @EBEBRATT-Ed was referring to this one which does seem to use an optic sensor on the gauge glass itself

    yes to the optic sensor.

    As far as hydrolevel goes they have had the parts available to mount a probe type on a gauge glass for years. It just took some searching in their catalog to find it.

    As far as the picture I posted above from another older thread of the sensor attached directly to the sight glass;
