Function

The circuit diagram shows a double headlamp system with H4-lamps, high-beam flasher and the control of the rear parking lights. The high-beam flasher switches on the high-beam, at the same time, a relay prevents the low-beam from lighting up. In an H4 bulb the two filaments may not be switched on simultaneously.

You can test the function of the control-lamp for the rear lights by clicking on them, thus simulating a light-bulb defect. This defect hs the effect, that in the respective reed-contact no current flows, causing the magnetic field, which closes the contact, to break down. There is an inverter shown next to the reed-contact on the right. It conducts a plus resistance (not shown) to the transistor exactly then, when the plus connection over the two reed-contacts is interrupted. The transistor then switches the control lamp on. 02/12
