The thing is it´s a Class IV-Laser inside and a car headlamp outside. The more you change about it the more you get from one to the other.
In cars these things must always be used with a stack of safety features:
- A reflector or lens that prevents direct view onto the phosphor
- An active surveillance of the phosphor disc, either as
- Conductive surveillance traces on the phosphor disc
- Active color measurement of the output light
- A speed limit: The laser light must only be active over a certain speed like 60 km/h. The idea is that if you are very near to a 2-ton laser that drives with more than 60km/h into your direction then the laser emission is the minor health risk.
There´s also one more thing about the speed: These laser light sources are super fascinating from a scientific point of view. But in real world driving scenarios they are rarely effective. They only are superior to a much cheaper LED if the output light needs to be focused to a very narrow high distance beam. That´s why the speed limit is okay for the car manufacturers: You need the extra-highbeam only if you are driving with high speed on a straight road. Then the better focusing of the laser-created-beam leads to really better illumination in distances around 500m in front of the car.
I personally do not motorcycle, I don't know if there is any need for that a focused light. I can only imagine that a main light and an intense but not unnecessarily focused highbeam are more important. And that´s easily achievable with state-of-the-art LEDs. Or to say it with other words: If you want maximum lumen (total flow of light) then LED sources are in each aspect superior to laser sources. Only if you need highest luminance (<=> ability to focus the light) then you may want to use lasers.
I can definitely not agree to the YT-video in the other thread that the laser inside these sources is harmless. It has 1 to 4.5W of optical power and definitely qualifies for Class-IV. Look into any laser safety table what that means.
