A few things that can help: reflective rim markings, a larger visual signature, and steady (not blinking) lights.

It looks dorky, but put a few pieces of reflective tape on your rims, together in one part of the rim, say two or three spoke gaps. This makes a moving patch of light that moves faster as your wheels rotate faster. If you cover too large an area, the light will become visually constant at higher speeds.

If you ride with a pannier, have good reflective material on the pannier. If you're picking out a rain jacket, look for one that has reflective material on the sleeves as well as the back. Look for shoes that have reflective material; tights that aren't solid black, etc. Human vision is better at judging the distance and speed of larger objects than small.

Blinking lights are great for grabbing attention, so by all means use them if they're legal in your area. But don't rely on blinking lights alone for night-time conspicuity. It's very difficult for many people to judge the speed and direction of blinking lights. Complement them with a steady light or large areas of reflective material to provide a continuous light for the eye to track once the blinking light draws attention.



The blinking LEDs may be what first draws attention to my commuter rig, but once you've noticed me, your eyes will have plenty of steady light to track me with.

Finally, don't cower in the gutter. Get out in the lane where bikes belong so drivers notice you sooner and recognize you as a vehicle before they're right on top of you.
