I don't know about this home-use version, but this here Edumund Scientific
catalog lists "LC Light Shutter Windows"; "On" time (clear) 10ms, "Off"
time (opaque) 30ms.  Problems are in the cost: 6"x6" = $89, 1'x1' = $170,
and you have to provide a small power supply: 60-90vac, 60Hz, 20ma/sq ft.

Me, I think the old trick of using a slave-strobe disguised as driving
lights oughta work admirably (and cheaply!), especially in something like
a Camaro where the fogs are adjacent to the front plate.
