I used to buy Cibie’ lenses for my cars, then install 55/85 halogen bulbs. Perfectly aimed and bright.

Yep, loved the pencil beams, they were like plane landing lights.

A narrower vertical beam spread is what’s needed. Older headlights had larger reflectors which allow for narrower beams.

Also, the incandescent headlamp bulbs have a straight filament which, if oriented horizontally, permits a very narrow vertical beam spread.
