Road Safety: Headlight Glare

Paul Girvan Excerpts

Wednesday 8th May 2024 Westminster Hall

That was a timely intervention from the hon. Member, as I was coming on to mention MOTs. The first point I put to the Minister is that he should bring together car manufacturers, the lighting industry, eyecare professionals, neurologists, driving organisations and other interested parties to gain a broader understanding of the problem of headlight glare and its true causes.

Secondly, the Minister should direct the National Institute for Health Protection, or another suitable body, to sponsor research to establish how vehicle lighting is causing discomfort in drivers, other susceptible individuals, and road users, such as cyclists and pedestrians. Thirdly, the research should be used to develop a set of realistic safety standards for headlights and other vehicle lighting, and to outlaw those that do not meet the standards.

Fourthly, legal limits should be set for the amount of blue light that vehicle headlights can have in their spectrum by setting standards for their colour temperature. Fifthly, as the hon. Member for Upper Bann (Carla Lockhart) has said, garages undertaking MOTs should be provided with guidance and training on how to recognise inappropriate after-market installation of LED bulbs and ensure that such cars fail their MOT. My sixth point is that the matter should be raised internationally, via the United Nations Economic Commission for Europe Working Party 29, and a request made that the informal working group on glare prevention be revived.

Two things are clear to me. First, car headlights should be better regulated to reduce the dazzle they cause to oncoming drivers. Secondly, it is not sustainable for the Government and the car industry to say that there is not a problem when the vast majority of motorists know that there is one, not just here in the UK but around the world. Is the Minister going to do what eight out of 10 drivers tell the RAC they think he should do, and take action to reduce headlight glare? The RAC thinks that the Minister will probably reply by saying that the UNECE has agreed that all new vehicle models introduced from 2027 will need to have automatic headlamp-levelling systems.

I thank the hon. Member for securing the debate. On that point, vehicle manufacturers are tied to a legal limit of 4,200 K, but bulbs can be retrofitted up to 6,000 K; there should be some legislation to ensure that that is addressed. I put a car through an MOT last week, and I know that all that is checked is that both lights are working and aligned within a certain parameter. That does not tell us the temperature of the light. Car headlights can be bought on eBay that go up to 6,000 K—they are illegal and not for road use, and that should be stated on the seal, but it is not in many cases. That is part of the problem.

[Martin Vickers]

My hon. Friend makes the case that I previously mentioned: there need to be more regulations than the simple MOT test as it is at the moment.

The problem of glare is affecting people now; and with drivers holding on to their vehicles for longer, it is going to be well into the next decade before any benefits—if there are to be any—are seen by road users. The 2027 date only applies to new vehicles, so if a current model is not due to be replaced until several years after 2027, it will only be at that point when it is fitted with the technology. The RAC is not aware that new lighting technologies, like LEDs, have been analysed in deciding that automatic headlamp levelling systems are the answer to glare. I hope that the Minister will give a positive response and say that the Department will indeed take the matter much more seriously than has been the case in the past.
