bluetooth alert light thingy?

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?

something like This?
other than that ive know that there are little stickers you can put on that flash when you phone receives a signal.

pick them up for like $2 at the markets

No, but at the GP a few years ago a few guys got some keyrings which light-up when your phone rings in close proximity. It wasn't bluetooth, it simply responded to the phone ringing.

that would work. thought it would have had to have been bluetooth.

but can't find them here or work out how to get one here.
(pom web sites don't seem to do international orders and postage seems
excessive when they do)
