If a complete headlamp unit has been replaced with a unit that was manufactured with HID or LED light sources, it must not be failed for ‘Light source and lamp not compatible’ but it must meet all other requirements detailed in section 4 of this manual specific to the type fitted at the time of test.
Vehicles with high intensity discharge (HID) or LED dipped beam headlamps may be fitted with a suspension or headlamp self-levelling system. If these systems have been fitted, they must work.
