headlamp
Vehicle's forward illumination
A headlamp is a light mounted on the front of a vehicle—what Americans usually call a headlight.
The word also refers to a light worn on the head, typically strapped around the forehead, leaving hands free for tasks in the dark: I grabbed my headlamp before heading into the cave.
