They have started trapping from the rear in South Africa using laser camera, so I want to move a sensor on the M40 to the back of my truck. Not sure whether to place above the #plate, which will be more difficult, or will it work 100% to the right of the tow bar. Not sure of the tow bar may block its line of sight? If they sit on the side of the road and aim at the plate, will the sensore be blocked by the tow bar, or not.
I have a pic, but dont know how to post it here...
