Abstract
1,253,175. Road traffic signals on vehicles. FAUSTO CARELLO & C. S.p.A. 24 July, 1970 [1 Aug., 1969], No. 35976/70. Heading G4Q. The rear direction indicator flasher lamps 10, 10<SP>1</SP> are connected in series with resistors 11, 11<SP>1</SP> shunted by contacts 12a, 12<SP>1</SP>a controlled by a relay 12, the relay circuit including a contact of a switch 13b which is closed when it is required to illuminate the parking lights 14. On operation of the direction indicator switch 7 the left or right-hand indicator lamps 8, 9, 10 or 81, 9<SP>1</SP>, 101 are flashed by the unit 5 connected to a battery 1. In daylight the switch 13b is open, relay 12 is not energized and contacts 12a, 12<SP>1</SP>a are closed so that full battery voltage, e.g. 12V, is applied to the lamp 10 or 10<SP>1</SP>. When switch 13b is closed the relay 12 is connected in parallel with a lamp 10 or 10<SP>1</SP> through a diode 18 or 18<SP>1</SP>. The relay is calibrated so that it requires about 8 volts for it to operate and open contacts 12a, 12<SP>1</SP>a. Thus 8 volts must appear across the lamp 10 or 10<SP>1</SP> before the resistor 11 or 11<SP>1</SP> is connected in series. This voltage builds up during a time interval in which the lamp filament warms up and thus ensures that the resistor is not connected too soon whereby the lamp filament would be too cold to emit a flash. In another embodiment (Fig. 3, not shown), the brake signal lamp has a series resistor controlled by a relay connected in parallel with that lamp and operating similarly to the relay 12.
