Abstract
To provide a warning for severe braking, a control button (8) operates a switch (5). This can either actuate a fog rear light or the flashers (4). When severe braking occurs the inertia switch (6) tilts on a pivot (16). Due to the lamp (17) and pivot (19) this results in the sliding of a rod (18); and a switch (6) is immobilised. At the end of braking, the switch (6) works again. When in operation, the switch (6) passes a heavy current to the flashers which then operate at higher frequency than normal. Alternatively, a powerful fog rear light is illuminated.
