MOT failure is partially incorrect

The light is naturally white. A filter of any colour cuts light output. The yellowish tint can reduce glare in some exceptional weather conditions.

What light? The sun? No that has a tint too. There are no natural perfect light sources. And I was talking about yellow vs blue tints.


Try using a equal spectrum RGB light output. It is not nice.

Blueish lights....that moment when they hit bumps...and you think they are "blues & twos" for a split second.

I think you'll find you have a pair of halogen bulbs in your car, not a pair of suns.

versus non-filtered halogen bulbs.

Getting an MOT is always hit and miss. You can have advisories one year that disappear the next even when it's the same MOT tester that carried out both MOTs.

why fit a stupid aftermarket bulb , "all weather?" , so did ford only specify dry warm days then they specified bulbs at development stage

change back to STANDARD bulbs

Why change the bulbs when there is no need to? The MOT tester is wrong.

4.1.4 Compliance with requirements
You must inspect all 'mandatory' headlamps fitted.

Mandatory headlamps consist of a matched pair of main beam headlamps and a matched pair of dipped-beam headlamps. These can be separate or a single pair of headlamps. Lamps are matched if they:

emit light of substantially the same colour and intensity
are the same size and shape that they are symmetrical to each other
Vehicles first used before 1 January 1931 don't need headlamps.

Buses first used before 1 October 1969 only need one headlamp. If 2 are fitted, neither the main beam or dipped beams need to form matched pair.

The colour of the light headlamps emit must be one of the following:

white
predominantly white with blue tinge
yellow
