I can see clearly now the Datsun has a new pair of headlights.
The car somehow missed a recall on the headlights not long after we bought the car. So it would seem that all of our complaints about them were well founded.
The lens in the projector dipped beams scorch deflecting the light away from the road.
Now with a new set of headlights we can at last see the road properly for the first time since owning the car!
