Generating both bulb and LED variations from the signal features, these signals are still the most typical style of traffic light on UK roadways. Together with the creation of anti-phantom, extremely visible Aston lenses, lights of 8 inches (200 mm) could be created to provide the identical output as simple lenses, so a larger floor area was unwanted.

The tiny light at the very best tells the driver in the event the car or truck's transponder signal is received through the traffic mild.
