Jerry, I wouldn't expect it would be much good for a headlamp as it does not have a directional beam, so don't get too excited.
The "Gentle lighting, no glare" means it will be a very diffused light. It may light a wide area, but it will not project very far down the road.
Headlamps need to have a bright and focused long range beam.
But if they did red ones, they might work as rear lights.
