We aren't riding large vehicles, so we have to put more effort into being more visible.

A combination of a blinking rear light and reflective gear gives us better odds.

You can easily spot a car at night, but not a cyclist.
In Europe blinking bicycle lights are allowed (white front, red rear).

Any blinking lights except indicator lights are often illegal in traffic.

Yeah, blinking lights make it more difficult to assess position and speed relative to cyclist, especially at night without street lights. At least get another one that shines all the time, or one that fades in and out but always shines at least a little, or a really good and big reflective one.
