Historically, France – of which Monaco is effectively a part for technical requirements – used to mandate yellow/amber headlight (we had to fit coloured adapters if we went to France at that time) but I think that has now changed. Also, there is another factor to consider – age. As we get older, our eyes lose the accommodation to deal with objects at different distances (certainly true for me) and we often begin to suffer from eye defects like cataracts, which cause blurred vision, and those factors cause problems in either very high or low levels. So, at night, rapidly varying light levels cause (at least me) a lot of problems when driving that I never suffered when younger. Finally, different peoples’ eyes vary quite a lot. I actually have pretty reasonable vision in very, very low light levels in which my wife can see nothing at all – so my sight sensitivity must be basically quite high, but it means I can’t cope with very high levels (be that the Sun or very bright car headlights). All these factors make the problems difficult to solve, and anything that makes the situation more extreme also makes them even worse.

Amazingly, I actually heard some people say the blue are better because you can see further at night and in fog. Years ago I once heard that in Morocco, the preferred color for car headlamps is amber. Never did verify if that was true. -Doug Douglas E Powell Laporte, Colorado USA <mailto:doug...@gmail.com> doug...@gmail.com <http://www.linkedin.com/in/dougp01> http://www.linkedin.com/in/dougp01 On Wed, Jun 22, 2016 at 11:08 AM, John Allen <john_e_al...@blueyonder.co.uk> wrote: Just had a routine info email from the ECM Web highlighting an interesting American Medical Association (AMA) article on the potential harmful effects of LED streetlights - see here: http://electricalmarketing.com/blog/ama-warns-harm-led-streetlights-blue-light?NL=ECM-07 <http://electricalmarketing.com/blog/ama-warns-harm-led-streetlights-blue-light?NL=ECM-07&Issue=ECM-07_20160622_ECM-07_825&sfvc4enews=42&cl=article_1_b&utm_rid=CPG04000000025478&utm_campaign=8880&utm_medium=email&elq2=0cf944f7f4f14ecbb045b2dbb57fc4de> &Issue=ECM-07_20160622_ECM-07_825&sfvc4enews=42&cl=article_1_b&utm_rid=CPG04000000025478&utm_campaign=8880&utm_medium=email&elq2=0cf944f7f4f14ecbb045b2dbb57fc4de I wonder what the effects could be in the future – and if anyone else, anywhere, has already picked up/investigated this subject?
