A type of light that is worn on the head, often used for hands-free illumination in dark places.

Headlamp → It is formed from "head" (from Old English "heafod", meaning the upper part of the body) and "lamp" (from Old French "lampe", meaning a device that produces light). The word "headlamp" refers to a lamp that is worn on the head or attached to a headgear, providing light in the direction the wearer is looking.
Think of a light source ('lamp') that is attached to the 'head' — this helps you remember that a headlamp is a lamp worn on the head.
