For comparison purposes, here's a photo with my camera flash at the lowest setting. You can compare the reflective intensity of various stuff here.
The helmet on top of the rack bag has the Blinky 5 with its retroreflective lens (the light is switched off here).
The red and white reflective tape on the fenders, a couple places on the front wheel, and the ends of the pedals is DOT Conspicuity Tape, which you can get from auto-supply stores in the US.
The amber tape on the rear rack struts is glass-bead tape (TrimBrite, similar to ScotchBrite).
The trim on the rack bag and the front panniers is ScotchLite.
I set a Jog-A-Lite reflective legband on top of the crankset, and draped my ANSI Class III vest over the top tube. That's Avery-Dennison 2-inch OmniBrite tape on the vest, if anyone's looking to get the tape itself.
Next on my list: get some more DOT Conspicuity tape and add some to both wheel rims (except I keep wavering because I want to build new wheels for this bike). I'm working on giving it a visual "signature" that really spells out B I C Y C L E whenever possible, so the circular shape of the wheels would be valuable.
