On my rig, I currently have several features I use in the hope it'll matter:
- A couple of spoke reflectors for each wheel.
- Pedal reflectors.
- Reflective conspicuity tape lengths along several of the bike's tubes (fork, down, seat, and seat stays).
- Clothing and jacket with reflective bits.
- Lighting, fore and aft.
I figure, every bit helps others see me better. Seems to induce people to give me a bit wider berth. And I haven't yet had a from-the-side or from-the-rear disaster narrowly avoided. So, perhaps it is resulting in people clearly seeing me, at those times when I'm out during the dawn/dusk periods. I certainly hope so.
