My daughter has a 1989 Nissan Sunny 1.6 GS. It has developed an
electrical fault, whereby when the headlights are dipped, the nearside
headlight does not light, and there is a regular clicking sound from the
Headlight bulb has been replaced, but still the same symptoms.
Relay box has been replaced, but still the same symptoms.
Nearside full beam and offside dipped/full beam work OK.
