The switch of fires of a stoplight (3) settles down in an arm over a brake pedal. It should not be confused to ventilating valves (1 and 2) systems of adjustment of speed. 4 – the block of management of blocking of departure of the car.

The switch of fires of a stoplight is in Audi over a pedal of a brake and is accessible only after dismantle of a reception pocket at the left (the head Salon).

If the brake pedal the switch pin is put forward is pressed and closes contact to stoplight lanterns.
