In a few sentences

In brief

The optical system determines where the light falls.

Useful to know

HELLA sees the headlights as a light distribution system, not just a high-brightness source. The exact housing and module are designed for a specific application. [1]

A bright spot in front of the car is not a complete assessment of illumination. On replacement, compare performance, handling, and required setup. Do not assume that visually uniform facade means the same optics inside. To describe a problem, it is useful to indicate whether a function is missing, there is an uneven light or a visible failure, instead of calling everything a "weak headlamp".
