Not directly related to the question put but may be of interest as it concerns LED lighting on cars. A consumer programme on our TV last night (Germany) concerned instances of motorists receiving fines in addition to points on their license as a result of being caught speeding by roadside cameras. One elderly couple were fined over six hundred Euros for doing more than 70km/h over the allowed limit. They of course swore blind that they always obeyed displayed speed limits and referred the matter to a solicitor specialising in traffic matters. Initial investigation and research by technicians both in the laboratory and by the roadside suggest the possibility of the frequency of LED vehicle lighting interfering with the frequency of roadside cameras resulting in false readings. In another example, and this was applicable to the elderly couple, careful inspection of the photograph that accompanies the fine notice revealed a very small portion of an overtaking vehicle and in addition one could see the exhaust pipe of a second vehicle that was obviously alongside the elderly couples vehicle. The points only became visible when the image was blown up to bed-sheet size. The elderly couple were reimbursed their fine and further investigation is taking place as concerns the reliability of roadside cameras especially as concerns the LED aspect of things.
