DescriptionThe car is equipped with two main beam headlamps.The main beam headlamps are switchedon:when the dipped beam headlamps are on, by pressing thelever towards the dashboard (stable mode)in 'flash' mode, by pulling the lever towards the steeringwheel (unstable mode)The circuit is protected by two fuses, onefor the right hand headlamp, one for the left hand headlamp.A warning light in the panel (rev countermodule) signals that the main beam headlamps have been switchedon.
Functional description The main beam headlamps circuit is operatedby the steering column switch unit H5 . When the switch is turned to the main beamposition, or when the 'flashing' contact is closed, the line whichsupplies the (left) F10 and (right) F11 headlampsreceives a supply controlled by the ignition. - - Each circuit isprotected by a fuse for the junction unit B1 : F7 forthe left lamp and F6 for the right one. The suppy line for the left headlamp alsosends a signal to the rev counter module E15 (pin 4 of connectorB) to light up the 'main beam headlamps on' warning light.
