Dim-dip lighting system - general informationBody electrical system / Dim-dip lighting system - general information
All models manufactured from late 1986 are fitted with a dim-dip lighting system, which essentially prevents the vehicle from being driven with the sidelights alone switched on.
When the ignition is switched on with the sidelights also switched on, the relay is energised, closing the internal contacts and supplying current to the dipped beam circuit via the resistor. This causes the dip filaments in the headlights to be illuminated at one-sixth dipped beam brightness. The relay winding is earthed through the headlight main beam filaments, so that the relay is de-energised when the main beam is switched on.
