[MENTION=392454]CliffordK[/MENTION], you're right. I'd forgotten about red on the sides towards the back. It appears to vary by state with some stating red is only allowed rearward of the center of the rear most wheel and some rearward of the front of the rearmost wheel. Most also defer to USDOT with a stricter standard rules except CA.

Still not sure about purpose. As a driver, when I see two white rings moving along it screams bicycle to me and I don't know that I've ever not known what direction they were traveling, even when stopped. Will red and white do the same or appear as some strange decoration?
