IMHO, it's six of one, half a dozen of the other. If you find another bike with signals equipped with running lights, chances are it isn't going to fit the Bandit's fairing (assuming you have the S model) and the connector won't match either (it's not even common among all Suzukis), so you'll be splicing more wires and trying to get a nice fit.
Nice idea though and if anyone's got a good solution, post it up!
