Morphology
The phrase is compositionally transparent: 'main' (primary) + 'beam' (shaft of light) + 'headlamp' (front vehicle lamp) clearly denotes the primary/bright beam produced by a car's headlamp. This is a regular, literal combination found across languages, so a B1 learner who knows the constituent words should be able to infer the meaning.
Etymology
Main beam headlamp gets its name from the parts main beam and headlamp, meaning a car's front light that sends a strong, central beam straight ahead. Because this bright, focused beam helps you see far on empty roads but can 'dazzle' other drivers, it is used only when there is no 'oncoming traffic'.
