Really? Since when specifically? It WAS always down to the judgement of the individual tester.

that would be due to the number of accidents happening due to drivers being blinded by badly fitted HID kits, Non compliant LED bulbs, badly adjusted beam patterns, now they just need to sort out all the one or two or three bulbs out cars on the roads

4.1.2 Headlamp alignment

You must inspect all dipped beam headlamps fitted.

The type of headlamp will determine whether the aim must be checked on dipped or main beam (see Diagrams 1, 2 and 3).

A flat top or other alternative headlamp dipped beam pattern is acceptable as long as all of the beam upper edge, including any ‘peak’ is contained within the appropriate tolerance band.

It's acceptable for masks or converter kits to be fitted to right hand dip headlamps to temporarily alter the lamp for use in the UK by removing the beam ‘kick-up’ to the right.

If driver’s beam aim controls are fitted, you should test the beam aim without altering the control setting. If this would result in failure for beam aim being too low, you should re-check the beam aim with the control set at its ‘highest’ position.

On vehicles with hydro-pneumatic suspension systems, it's necessary to have the engine running when checking headlamp aim.

To check the aim:
1.Position the vehicle on the designated headlamp aim standing area.
2.Align the headlamp aim testing equipment to the vehicle in accordance with the manufacturer’s instructions.
3.Determine the appropriate headlamp beam image and its aim (see Diagrams 1, 2 and 3).

For 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.

You mustn’t carry out repairs during an MOT test, but you can make minor adjustments to the headlamp aim.

European type – check on dipped beam

European type lamps have one of the following:
•an asymmetric dipped beam pattern with
◦a horizontal cut-off on the right
◦a wedge of light above the horizontal towards the left, known as the 'kick up'
•lens may have European approval mark

For European type lamp to pass, you must make sure that:
•beam image 'kick up' is visible on the screen
•for headlamps with centres at 850mm or less from the ground, the beam image horizontal cut-off is between the 0.5% and 2.75% horizontal lines
•for headlamps with centres more than 850mm from the ground, the beam image horizontal cut-off is between the 1.25% and 2.75% horizontal lines
•white light doesn't show in the zone formed by the 0% vertical and 0.5% horizontal line

I eventally got the Morimotos in. The performance is excellent. Very sharp cut off no scatter or dazzle. Instant main beam and great foreground illumination. A real struggle to do though.
Pinched the idea from this article:- https://rennlist.com/forums/924-931-944 ... r-mod.html
