Welcome to Lightmare ......
Our organisation has been formed to fight the growing road safety issue of blinding lights which diminish a driver's ability to perceive hazards. 

Four prominent professors of ophthalmology have declared that these lights are dangerous to the human eye:

Peter Heilig, University of Vienna (Expert Opinion)
John Marshall, University College London(Daily Mail May 2017)
David M. Kleinman University of Rochester New York (CBS May17)
Geoff Roberson, Association of Optometrists (BBC April 2011)

All the manufacturers can say is that "they meet the regulations" surely from the thousands of complaints it proves the regulations are wrong.

Rather than saving lives, these lights are killing people - why are the authorities doing nothing? why are they permitting this to continue?
The Authorities are allowing this "Lightmare" to escalate, they are putting the most vulnerable and less conspicuous road users at risk - pedestrians, cyclists and motorcyclists.

UK DfT announce UNECE Working Group formed stating:"an Informal Working Group of experts will develop solutions for the concerns you have raised with respect to glare and vehicle lighting".

  # Oct 2015 - Blinding Lights blamed for soaring crash rate - a gimmick too far?
2014 road accident statistics make sorry reading, since blinding lights were introduced instead of falling UK and EU accidents have increased 
- a problem bigger than the VW crisis! 

Our aim is to persuade the world regulators (NHTSA and UNECE) to limit eye damaging light intensity:-
   #  High Intensity Discharge Xenon headlights (HID-Xenon) - can cause temporary blindness

   #  Misuse of brake and fog lights - contravention of highway codes

   #  Over-bright Daytime Running Lights (DRL)
- the EU have set maximum brightness to 1,200cd
    to compete with the sun - the Japanese proposed a more acceptable 200cd = bright sidelights

Manufacturers and Government appear not to care about the dangers of blinding lights.
In this website we explain why a driver's vision is affected by blinding lights.
We document the growing body of Expert ophthalmological opinionLegal opinion and  Media  coverage
