Intermittent light can attract attention at night.

On the road, I run solid white forward on both helmet and handlebars. When I see a situation forming ahead, like a vehicle approaching from the right, I shake my head left and right to attract attention.

I do have a low-power flasher on the front of my helmet, in addition to normal headlight mounted to the top. There have been times I have turned it on briefly at night to attract attention.

I believe, but cannot prove, that a change in the visual scene increases conspicuity. That’s why I will add intermittent lighting when I am at risk, and return to steady when I’m not.

MUP riding at night requires that you not impair the vision of other approaching users.
