Baroness Vere of Norbiton (Con)
I was just trying to point out that the evidence noted by the noble Baroness, Lady Hayter, was from a survey. The Department for Transport did scientific research into this matter in 2018. As I said, the conclusion overall was that there was no direct adverse health effect from LED light emissions. However, that does not mean that we do not continue to take a great interest in this. We recognise people’s concerns about dazzle and glare, which, indeed, is why we have pressed the international community to make some headway.
The Earl of Clancarty (CB)
My Lords, I am not sure the health effects are the real problem. I have read that quite a few accidents have been caused by this, so maybe there is quite an urgency to the matter raised by the noble Baroness, Lady Hayter.

I can provide some further evidence. Between 2010 and 2020, so a 10-year period, dazzle was a contributory factor—and indeed there can be many contributory factors; you do not just have to have one—in 0.25% to 0.34% of collisions. Far less than half a per cent have dazzle as a contributory factor. However, we have also looked at the trend over time and there has been no increase in the amount of dazzle caused. Again, we will continue to look at all evidence, but I can say that a very small number of collisions even have it as a contributory factor.
