Title: High visibility is a plus!
Review: Anyone who rides a bicycle or motorcycle would benefit from this product. They replace the valve cap, so if you can put air in a tire you can install these! I bought these for my wife at her request, but I was sufficently impressed with the added visibility of the bike at night that I am buying some for myself.
