This may not be the case- these are the proposed changes from April this year.
Products on the lens or light source that obviously reduce the light's intensity or change its colour will become a reason for failure – applies to front/rear position lamps, registration plate lamps, stop lamps, rear fog and direction indicators,
Headlight requirements are updated to take account of the particular characteristics of High Intensity Discharge (HID) lamps.
HID headlights can cause dazzle if they are dirty or aimed too high so car manufacturers must fit headlamp cleaning and levelling systems. A car will fail if a mandatory headlamp cleaning or levelling system is missing, doesn't work or is obviously defective.
Vehicles fitted with aftermarket HID systems must also be fitted with properly working washer and levelling systems.
If a headlamp bulb is not seated correctly the resulting beam pattern will be indistinct and this will result in a test fail.
