I had a pair of Cibie Z-Beam halogen headlights back in the late ‘70s on a 1972 Porsche 911T. On low-beam, they produced a bright white pattern that shown straight in front, but with bias toward the right hand side of the road so oncoming drivers weren’t blinded.
The Z-beam pattern only applied to the low beams. On high-beams you could see into the next state, and they vaporized small animals that crossed in front of the car.
Yea, love the photon bombs, never had to worry about over driving your headlights.
