went through one the other day in the pouring rain low vis at night never saw it was dong 50 coming out of Leicester at 11pm though it was a 40 so only 10 over, now turn's out it was a 30 .. so 20 over
the camera is damn near impossible to notice in those conditions the only thing that gave it away was the lines on the floor
now what i have found out is they flash, but thats about it, never saw it flash but in the conditions i cant really say if it did or not.
any one got any more info, and can they catch bikes ?
