Why handlebar mounts for trail riding?
I understand why we need lights mounted on our bikes, rather than our helmets, when we are riding on the road: we need the car about to turn left into us to see us, even when we are looking to the side, so we need a light pointing forward.
But what is the benefit to having a bike-mounted light on the trail? When I'm riding on the trail, there are no cars to hit me, and all I care about is lighting up where I'm looking. So why would I want a light on my bike instead of my helmet?

For me when combined with a helmet mounted light it helps with depth perception.
