Satman recently pointed out to be that my rear number plate was 'a bit reflective' and when you closely at it he's right. It has a homecomb pattern on it that I haven't noticed before. When you try to take a flash photo of it you can't see the numbers anymore as you just get glare, and it doesn't seem to matter what angle you take it at. I tried a number of times with a digital camera.

Whats more it seems like all Cerbs I've seen since have the plate as well. Does this mean all Cerbs have stealth numberplates as standard??

You still get caught. My front one is i think, but i still got done. (video in van. Not flash) Not sure whether you still would get caught by Truvello, as they use infra red, and on your front plate. Besides, I now dont speed,(honest yout honour) as i got 6 points in 6 days.

The rear plate is like those on griffs and chims, ie backlit. In order for the light to get through it is made of something a little different to the normal plate.

If you REALLY want a stealth Cerb, you could always try: www.priva-plate.com/

Now, if you link the on/off switch of that via a relay to the scamera warning buzzer on a RoadAngel/whatever, it could be amusing.

Nice one priva plate, anyone thinking of trying it. Actually what I want is one that fights back zapping all who try to photograph it!

The highly reflective plates are indeed for backlighting purposes. The reflective material is 3M diamond grade reflective, or a similar product from another manufacturer. It is the stuff used on "battenburg" police liveries and some road signs. It is much more reflective than normal, and reflects from a much wider angle, so may well confuse flash photography, but not all speed traps use flashes! Normal reflective films block the light of the unique TVR backlit numberplate out.

An interesting film I have seen on the market is a clear laminate which when viewed straight on is optically clear, but when viewed from an angle goes white. Theoretically, this may also give "stealth" qualities to your plate, as a camera looking down from a high angle would see only a white rectangle. The film was actually developed in Japan for application to glass elvators, to prevent people being able to see up womens skirts as the lift went up in the air! It is very expensive though, at about £130 per square metre.

A much cheaper option is the £15 privacy glass you can get for a CRT monitor that does an identical thing. I figured that a driver in pretty much any offroader would be looking from at least as steep an angle as a scamera, though... so you'd likely get stopped *very* quickly.
