I had reason to ride my motorbike at night on roads I didn't know last week. I rarely ride at night.
2 things were painfully obvious.
With a half decent headlight the glare from reflective road signs is way too bright, it is often difficult to see what is beyond them particularly on modest sized A roads where the signs can be quite large and close to the road. Some years ago there was a process of painting some with brown gunge to reduce the glare, so it is obviously a recognised issue.
Second was that modern trucks are festooned with stupidly ridiculous amounts of intense red lights and reflective tape all over the back. Absolutely stupid and bonkers. They are huge big things and are easy to see, no need to make them into Blackpool illuminations. I don't know how much is regulation and how much is just silly fashion. I counted 16 separate lights on the back of one artic, plus the red tape outlining the shape.
