We constantly search for ways to improve night-riding safety through better vision awareness.
This article explains what we have found regarding yellow light vision so far.

Photographs or videos are a fantastic way of showing visual content, but they are technologically “biased” in the case of yellow light vision.

Why?

Because better vision under night rain or snow storms depends finally on what the human eye perceives, and the eye behaves differently than the camera.

Night-driving truckers are the drivers who most commonly endure storms that impair vision. They are always willing to try technology that eases transiting those events at night.

Through them, we learned that cameras reduce the reflecting glare of raindrops or snowflakes under white light.

Truckers claim to see better if they see through the storm with a telephone camera, which is one of the reasons why night vision SWIR cameras exist.

However, no vision gadget outperforms the human eye if you can change its visual environment to enhance its capabilities.

That is why we became interested in yellow lighting.

We keep referring to Dr. John D Bullough and Dr. Mark S Rea’s paper because they confirm the better vision phenomenon (with yellow illumination) from the biological (human eye) perspective.

The paper confirms that digital photographs or videos cannot reproduce the actual human eye experience under a night storm.

It clarifies that the moving raindrops or snowflakes create what they call “visual noise” that “distracts” the eye from clear vision.

Consequently, it also explains why the yellow light makes no significant difference under fog. Since tiny fog droplets are steady, no “visual noise” is present.

We started our field test to learn if the yellow light improves vision under night storms, installing the yellow option on the low beams of an interstate truck to confirm if the the color added to safety.

It turned out that the driver loved it. He confirmed that yellow improved his vision while under night bad weather.

However, since the internet is still inconclusive regarding the yellow light vision improvement, I decided to do my personal test to make it so that my readers can do it, too.

I bought this flashlight on Amazon and waited for a night storm. I chose a dark outdoor spot and my umbrella and tried the color switching from white to yellow, pointing to a faraway obstacle.

If you do that, consider trying our white yellow headlight bulb versions to ride safer at night!
