I don't drive much but I do a lot of night riding with groups. On brevets, riders will be stretched out ahead and behind.

Some riders simply disappear into the night, others can be seen from a quarter mile away or more.

In darkness, I find solid lights show up better than blinkies. That's controversial, I'm sure. Reflective vests really pop. Reflective ankle bands are great when visible but are often obscured. Taillights mounted on seat stays disappear when the road has a slight bend. Lights mounted on bags disappear because they're pointed any which way. Headlights that light up a patch of road are sometimes the last thing to disappear in the distance.
