So I found an inexpensive pack of four blinkers with replaceable batteries with attachments for the bike and my person on amazon.

Excellent for use with the hotshot.
What mirrors would y'all recommend? There are tons of brands, fixed, flexible, some that attach to the handlebars, to the end of handlebars, to helmets. I don't know what to look at. I want to keep price down, but get something I can rely on.
