Lately, I’ve been hearing people say that nighttime riding is hard to see\u2014maybe it’s just aging eyes?
I found it strange that even with such bright street lights, visibility is still poor.<\/p>\n\n\n\n

It occurred to me during a test ride.

The oncoming vehicles’ headlights are too bright, and their beam alignment seems off…
What do you think?<\/p>\n\n\n\n\n\n\n\n

Back in the day, when I was young, I thought smoke shields were cool.
But as I got older, from my twenties onward I’ve been a clear shield person, and still am.

I tried yellow shields for a while, but I heard they weren’t good for the eyes, so I stopped.<\/p>\n\n\n\n

Let me get back to the glare issue.
Oncoming vehicle lights are clearly too bright.
At some point, running lights on high beam became the norm…
It’s not wrong, but in areas like central Tokyo where you’re constantly passing other vehicles, low beam is more considerate.<\/p>\n\n\n\n

Road Traffic Act, Article 52, Section 2
When passing other vehicles at night or driving immediately behind a vehicle ahead, you must dim or turn off the headlights and operate the lights accordingly.
The light operation that constitutes this dimming is switching to ‘passing<\/strong> headlight (low<\/strong> beam)’.<\/p>\n\n\n\n

If you can’t see anything at all in the dark, it might be aging.
It would be nice to have a properly polarized shield…I wonder if one exists?<\/p>\n\n\n\n

Both oncoming vehicles and rear-view mirrors are so bright that I’m nervous about test rides at night lately.
I’ll be careful!<\/p>\n","protected":false},"excerpt":{"rendered":"
