Headlamps
fitted to motorcycles fall into two main groups, ie those which are intended to
be set on main (driving) beam (diagram 2) and those on dipped beam (diagrams 1
& 3).
Some of the more prominent features which will aid identification are given below
and on Pages 3, 4 and 5.
Machines with a single beam headlamp first used on or after 1 May 1995 so
constructed to be incapable of exceeding 30mph/50kph on the level with an engine
capacity not exceeding 50cc are only required to have a dipped beam, provided
a rear position lamp, stop lamp and rear reflector are also fitted (see also information
notes at 1.2 headlamps).
On machines without a battery or with an insufficiently charged battery
it will be necessary to run the engine. If an automatic transmission is fitted
the light output may be low but the hot spot can usually be identified.
Check that the tyres are not under-inflated.
A flat top dip beam pattern is not a reason for rejection.
An alternative headlamp dipped beam pattern (not being one of the examples) is
acceptable providing all of the beam upper edge, including any “peak” is contained
within the appropriate tolerance band. |
A1. USING A RAIL
MOUNTED HEADLAMP AIM TESTER
Locate the machine on the area designated as the ‘standing area’ for the headlamp
test.
Clamp the front wheel or otherwise support the machine so that it is upright and
in the straight ahead position.
With an assistant sitting on the machine in the normal riding position align the
beam tester with the longitudinal axis of the motorcycle and align the centre
of the collecting lens with the centre of the headlamp under test in accordance
with the equipment manufacturer’s instructions.
Switch the headlamp to the beam on which the headlamp is to be checked.
Follow the instructions given by the manufacturer for the particular headlamp
aim equipment being used.
