looking at the osram nightbreaker laser, I am thinking that the ultimate hagogen bulb should be someting that has similar window cut like nightbreaker laser with completely opaque coating. It could be a + 200% bulb with 150h lifespan,and that's it ,not much can be done with it anymore,right? in the near future,all cars will be equipped with LED headlights or similar new light source.So the demand for halogen bulbs will continue to decline, large companies will no longer willing to spend money to further improve them.
