You must fail a British American type lamp if its ‘hot spot’ centre is any of the following: a circular lens which might be marked with a figure ‘1’ followed by an arrow indicating the direction of dip.a symmetrical main beam pattern with a central area of maximum intensity (‘hot spot’).Criteria for European beam headlamp aimīritish American headlamp - check on main beamĬheck British American type headlamps on main beam if they have: white light does not show in the zone formed by the 0% vertical and 0.5% horizontal lineĭiagram 1.the beam image horizontal cut-off is between 1.25% and 2.75% below the 0% horizontal line (for headlamps with centres more than 850mm from the ground).
the beam image horizontal cut-off is between 0.5% and 2.75% below the 0% horizontal line (for headlamps with centres at 850mm or less from the ground). a wedge of light above the horizontal towards the left, known as the ‘kick up’Įuropean type lamps might have a European approval mark, usually a letter ‘E’ in a circle or an ‘e’ in a rectangle.įor a European type lamp to pass, you must make sure:. European type - check on dipped beamĮuropean type lamps have an asymmetric dipped beam pattern with: You must not carry out repairs during an MOT test, but you can make minor adjustments to the headlamp aim. Switch on the appropriate headlamp beam and check the aim on the screen.įor complex lens systems - meaning those that have more than one lamp behind a single lens - make sure the test equipment is aligned exactly on the centre of the dipped beam pocket. With an assistant sitting on the motorcycle in the normal riding position and holding it in an upright position, align the screen’s vertical zero line with the motorcycle headlamp’s centre line.Īlign the horizontal zero line with the horizontal axis of the headlamp using the headlamp height measuring equipment. Position the motorcycle on the designated headlamp aim standing area with the headlamp lens the appropriate distance away from the aiming screen, and its longitudinal centre line at a right angle to the screen. Then align the centre of the collecting lens with the centre of the headlamp as per the aim tester equipment manufacturer’s instructions.ĭetermine the appropriate headlamp beam image and its aim (see Diagrams 1, 2 and 3).įollow the aim tester equipment manufacturer’s instructions. With an assistant sitting on the motorcycle in the normal riding position and holding it in an upright position, align the beam tester with the longitudinal axis of the motorcycle. Position the motorcycle on the designated headlamp aim standing area. Using a rail mounted headlamp aim tester: The light intensity may be low if the motorcycle is fitted with automatic transmission, but any hot spot can usually still be identified. If a motorcycle does not have a battery or the battery does not have enough charge, you must run the engine to be able to inspect the headlamp alignment. You can pass a right hand dip headlamp fitted with masks or converter kits that temporarily alter the lamp for use in the UK by removing the beam ‘kick-up’ to the right. You can pass a flat top or other alternative dipped beam headlamp, as long as all of the beam upper edge, including any ‘peak’ is contained within the tolerance band. The type of headlamp will determine whether the aim must be checked on dipped or main beam (see Diagrams 1, 2 and 3). (ii) missing, inoperative or more than ½ not functioning in the case of LEDĪll dipped beam headlamps must be inspected for headlamp alignment. 
(i) with up to ½ light sources not functioning in the case of LED You must assess damaged or repaired lamps for security, colour, light output and durability. If the motorcycle does not have a battery or the battery does not have enough charge, you must run the engine to be able to inspect the headlamps.Ī ‘light source’ means any bulb, LED or other means of emitting light. If the light intensity of the lamp is significantly reduced, it should be failed. Headlamps’ colour must be one of the following: On twin headlamp systems, one or both headlamps may operate on either beam. has a maximum speed up to 30mph or 50km/h.was first used before 1 January 1972 and has an engine capacity of less than 50cc.have had their front and rear position lamps permanently disconnected, painted over or maskedĪ motorcycle does not need a main beam headlamp if it:.are not fitted with front and rear position lamps.Headlamps are not needed on motorcycles that: Apart from headlamp security, the check only applies to mandatory lamps. A motorcycle or motorcycle and sidecar must be fitted with one headlamp, although additional headlamps may be fitted.
