HEADLAMP CONDITION
Method of Testing
1.
2.
3.
With the headlamps switched to main or dipped beams, check that each headlamp shows a light of the same colour (white or
yellow) of such intensity as to sufficiently illuminate the road in front of the vehicle.
Check the condition and colour of the headlamp glass and reflectors.
Check the operation and security of the headlamp, dip switch and the headlamp main beam warning light.
NOTES
1. Headlamps should consist of either two or four lamps, or one lamp in the case of an electric vehicle
incapable of exceeding 40km/h (24mph).
2. Headlamps are not required to be e-marked.
3. Where a dipped beam is so far out of focus that it cannot be picked up by the headlamp tester, then it
should be failed.
