1.7 Headlamps
Information
Method of Inspection
This inspection applies to all obligatory headlamps fitted.
Headlamps are not required to be fitted to vehicles used only during the hours of daylight, which are fitted with neither front nor rear position lamps, etc. (See 1.1.A).
Vehicles equipped with High Intensity Discharge (HID) or LED dipped beam headlamps may be fitted with headlamp washers and a suspension or headlamp self levelling system.
Where such systems are fitted, they must work; however, it is accepted that it may not be possible to readily determine the functioning of self levelling systems. In such cases, the benefit of the doubt must be given.
Headlamp washers may work in conjunction with the windscreen washers (when the dipped beam headlamps are switched on) or by a separate switch.
HID lamps may be identified by:
. taking a few seconds to reach full intensity
. having a bluish tinge to the light
. having an igniter module/inverter behind the headlamp
. having ‘DCR’ marked on the headlamp lens.
HID headlamps use high voltage and extra care should be taken when inspecting these items.
