Virtually every new automobile has LED lights for the very reasons you list, and, they're a more natural light.
I tend to agree with Powderman on this one Cal. The OP wasn't asking what every NEW automobile comes equipt with and it's irrelevant considering an H4 LED bulb is a retrofit and not optimized for the reflector. My H4 LED (similar to Cognito moto) is no where near as capable as the halogen H4.

FJ, you missed the point of my reply. It was a response to the characteristics of LEDs being subordinate to an H4, which they're not. Agree that the reflector design is extremely important to the effectiveness of
any bulb, but I can assure you from personal experience, that LED headlights for motorcycles are far, far brighter and cast a much better beam than an H4 halogen. I've seen th LED bulb Cognito sells compared side-by-side with an H4, and an LSL LED headlight (similar to the TruckLite) and the H4 loses in all departments. The LSL is hands down the winner, but the LED H4 is much better than the H4 halogen. And they're much better than the stock units.
Beam focus, spread and projection are all important elements, and a function of the reflector. Illumination is the function of the bulb. So a better bulb in a better reflector gets you a better headlight. Pure science.
