I saw these advertised somewhere but I can't remember where. A light you attach to your handlebars that flashes when you get a call on your mobile
got split up on a ride through heavy traffic and took forever to get in contact as one of us was riding when the other rang and vice versa. finished up with one of us in frankston and the other in burwood.
most of the time we don't want to talk to each other so I don't want a headset.
has anyone else seen them?
