You would think that, but most bike headlights are just throwing as much light as possible in a 180 degree arc so the rider can spot drop bears and other related hazards. It is so rare for someone to have a light that directs the photons downward like an automotive headlight. When I was looking for a headlight my local bike shop didn't sell a single model that had that feature, in fact they made a big deal about having 180 degrees of illumination and 1000 lumen output and an oncoming traffic blinding strobe mode. Also, the bike shop stock was hilariously overpriced for what it was. $5 of flashlight components in a plastic case and they wanted $80. It felt like the entire industry was being grossly overcharged and underserved.
I had to construct my own headlight out of a flashlight and a homemade deflector.
