I like to be seen and if wearing bright colors or saftey vests help my visablity I am all for it. For long trips I have stretch the saftey vest over my seat bag. I often wear a bright white tee shirt especially in low light or cloudy days. (Doesn't work on snowy days) The same holds true when buying a car. Studies show certain colors are more visible and your chances of avoiding crashes are greatly increased. BTW white is the best car color.
