As someone who doesn't trust his car's automatic high-beam, 100% this. Are the lasers bright enough to be a health risk? You wouldn't attach a high power laser

Are the lasers bright enough to be a health risk? You wouldn't attach a high power laser pointer to a moving vehicle either.
- semi-extrinsic 8y agoAFAICT these things don't actually emit laser light, they use a high power laser to stimulate some sort of phosphorus-like material that then emits incoherent white light. The point is then that this secondary light source is very small (compared e.g. to LED with similar lumens), so the light can be much more easily focused by optics.
