I also have reflective tape on my crankarms. Seems like a decent approximation of pedal reflectors (or even pedal lights—Redshift makes light-up pedals). Also a fair amount of reflective tape on my rims, which won't help if the motorist is dead-ahead or dead-behind, but are visible when there's a bit of offset. The taillight I'm currently using is a Lezyne "strip" that has 5 LEDs in a row, and I have them lighting up in a scrolling pattern, so there's a bit of movement without a change in overall brightness. I've seen other taillights that have some kind of scrolling pattern.

I dislike ankle cuffs, but for night riding, I do have socks with reflective dots.
