Headlight Safety Performance Rating (HSPR) - GTB Recommended Practice

Today’s light distributions of modern headlamp systems can be adapted in traffic situations, according to the oncoming and preceding vehicles, by combining a passing-beam with horizontal cut-off shape and an ADB lighting function. The purpose of this system is to avoid a critical glare level for other traffic participants, while providing maximum illumination range for the driver.

Therefore, for a complete, fair and objective rating of modern headlamp systems, all main lighting functions like passing-beam, ADB and driving-beam must be considered.

This “Recommended Practice” aims to define an objective standard for headlamp rating systems including ADB functionality.
