[FONT=Arial,Bold][FONT=Arial,Bold]Information Method of Inspection Reason for Rejection[/FONT]
[/FONT]
1. Check the presence, security and operation of
the headlamp switch.
2. Where HID or LED dipped beam headlamps are
fitted, switch on the headlamps and check the
operation of any headlamp levelling and
cleaning devices fitted.
3. Check that the vehicle is securely fitted with
obligatory headlamps, as follows:
•
a matched pair of main beam headlamps,
and
•
a matched pair of dipped-beam headlamps
[FONT=Arial,Bold][/FONT]
[FONT=Arial,Bold][FONT=Arial,Bold]Note: [/FONT]

[FONT=Arial,Bold]
[/FONT]Main and dipped-beam functions may be
provided by a single pair of headlamps.
1. A switch missing, insecure or faulty.
2. A headlamp levelling or cleaning device
inoperative or otherwise obviously defective.
3. A missing, insecure or obviously incorrectly
positioned obligatory headlamp.

[FONT=Arial,Bold]
[/FONT]Class 3 vehicles may require only one
headlamp (see Section 9.1).
[FONT=Arial,Bold][/FONT]
[FONT=Arial,Bold][FONT=Arial,Bold]Note: [/FONT]
[/FONT][FONT=Arial,Bold][/FONT]
[FONT=Arial,Bold]
[/FONT]The precise position of headlamps is not
part of the inspection, but check visually that the
lamps are at about the same height and the
same distance from each side of the vehicle.
[FONT=Arial,Bold][/FONT]
[FONT=Arial,Bold][FONT=Arial,Bold]This inspection applies to [/FONT]
[/FONT][FONT=Arial,Bold][/FONT]
[FONT=Arial,Bold]
[/FONT]all obligatory
headlamps fitted.
[FONT=Arial,Bold][/FONT]
[FONT=Arial,Bold][FONT=Arial,Bold]Headlamps are not required to be fitted to[/FONT]
[/FONT]
vehicles used only during the hours of daylight,
which are fitted with neither front nor rear position
lamps, etc. (See 1.1.A).
[FONT=Arial,Bold][/FONT]
[FONT=Arial,Bold][FONT=Arial,Bold]Vehicles equipped with High Intensity Discharge[/FONT]
[FONT=Arial,Bold](HID) or LED [/FONT]
[/FONT][FONT=Arial,Bold][/FONT]
[FONT=Arial,Bold]
[/FONT]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.
[FONT=Arial,Bold][/FONT]
[FONT=Arial,Bold][FONT=Arial,Bold]HID lamps may be identified by:[/FONT]
[/FONT]
•
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.
[FONT=Arial,Bold][/FONT]
[FONT=Arial,Bold][FONT=Arial,Bold]HID headlamps use high voltage [/FONT]
[/FONT][FONT=Arial,Bold][/FONT]
[FONT=Arial,Bold]
[/FONT]and extra care
should be taken when inspecting these items.
4. With the headlamps on, switch between dipped
and main beams checking that:
a. each headlamp illuminates immediately it is
switched to either dipped or main beam
b. either:
•
all main beams are switched off by one
switch (dip switch) leaving a matched
pair of dipped-beams switched on, or
•
the main beam headlamp reflectors are
deflected by a driver’s control, to make
them dipped beams
c. on vehicles first used on or after 1 April
1986, the ‘tell-tale’ illuminates when main
beam is selected.
4.
a. A headlamp does not operate immediately
when selected on dipped or on main beam
b. operation of the dip switch does not:
•
extinguish all main beam headlamps,
and leave on at least one pair of dipped beam
headlamps, or
•
deflect the main beams to make them
dipped beams.
c. the ‘tell-tale’ does not illuminate when main
beam is selected.
