direction indicators (left or right) switched on by the left steering column switch (short lever). Alarm mode (all direction indicators flash) activated when the corresponding button is pressed. The flashing of the lamps is provided by a relay-breaker type 231.3747, mounted on a stud under the instrument panel. If one of the turn signal bulbs burns out, the blinking frequency of the remaining bulbs and the indicator lamp doubles. In normal mode, the flashing frequency should be 90±30 cycles per minute under a load of 92 W at an ambient temperature of -40 to 65°C and a voltage of 10.8 to 15 V.
