Having received a photo ticket from a toll booth camera that was pointed almost 
directly into the setting sun (the picture of my car clearly showed the sun I 
was driving into) I'm a bit dubious about the ability of a small UV lamp to 
screw up the camera.  Remember, these are high resolution digital units, not 
old fashioned plastic film units.  The computer digitizing the pixels does not 
suffer film washout.  This is why a digital camera and computer can take and 
create an excellent photograph of the darkened interior of a building through 
the doorway or window, while outside in the bright sun.

As for the dire warnings about using a UV lamp and how difficult they are to 
obtain, bovine feces.  They are commonly sold in pet stores as part of a pond 
or aquarium filtration unit.  They are called UV sterilizers.  Not cheap, but 
quite common and available.  

One of the most effective (if ugly and illegal) methods of hiding the licence 
plate is mechanical.  From a bunch of narrow and long tubes covering the plate 
making it only visible when viewed straight down the tubes, to a James Bond 
like flip up plate.  A less ugly technique of the tubes would be a derivation 
of essentially a polarized lens over the plate.  There are some of these 
around, but I've never seen one that was anything but straight line reflecters, 
so if the camera is off the blocked angle, the plate is clearly visible to the 
camera.  You would want a series of baffles cut at different angles like a 
honeycomb.  This I have never seen on the market.
