If this situation occurs the vehicle presenter should be issued with an advisory notice recording the above and it should also be recorded on the carbon copy of the VT20.

A motor bicycle first used before 1 January 1931 does not need a headlamp.

A motor bicycle is only required to have a dipped-beam headlamp (but may also have a main beam) if it:
. was first used on or after 1st May 1995 and cannot exceed 30 mph / 50 kph with an engine capacity not exceeding 50cc. or
. was first used before 1 January 1972 and with an engine capacity of less than
. any machine having a maximum speed not exceeding 50km/h/30mph

1. Check the headlamp emits a WHITE or YELLOW light

2. Check that the illumination of the
headlamp is not affected by the operation of any other lamp or the horn and does not flicker when tapped (see information column).

3. Check the condition and security of the headlamp.

1. The headlamp does not emit a light which is substantially WHITE or YELLOW in colour

a. does not have at least one headlamp which illuminates when selected on:
(i) dipped beam

(ii) main beam

b. operation of the dip switch does not
(i) extinguish all main beam
headlamps and leave on at least one dipped beam headlamp, or

(ii) deflect the main beam/s to make them dipped beam/s.

a. a headlamp missing or so damaged or deteriorated that its function is impaired. (See info column)

b, an insecure headlamp.
Twin headlamp systems
On twin headlamp systems only one or both headlamp may be illuminated for either dipped or main beam. Each headlamp that can be illuminated on dipped beam must meet the requirement for dipped beam headlamps. Twin headlamps must be mounted either one above the other or symmetrically without regard to any side car and not more than 200mm apart measured from the edge of the reflecting surface. The tester should advise if both headlights should illuminate for either function and only one does so.

On machines without a battery or wtth an insufficiently charged battery, it will
be necessary to run the engine.
4. Check the condition operation and security of the switch. 4. A faulty or insecure switch.
