I have the Rizoma Club signals pictured below in black. These are tiny, but very bright and I love them. I have the integrated rear brake-run-signal ones in back with a fender delete and the normal ones on the front*. Rizoma stuff is expensive, but it is amazingly well made and designed -- my signals have 25000 kms of all weather riding on them and still look brand new.

*The Club L turn signals looks awesome, as they are a white run light and a normal turn signal. I don't think you can run these on the CB though, as it is wired to run the front signals all the time as running lights and this would make the turn signal override the run on the Rizomas. Just food for though if you think about going this direction.
