I don't think it matters what kind of bar you run, about the only place most lights end up, if bar mounted, is close to the stem. I mean... is it even possible to put a light anywhere else on a handlebar? Many lights make the job easy for you by mounting two lightheads in a single housing. I hope an earlier poster who alluded to two lights giving oncoming drivers the impression that a car was coming towards them... ... well I hope he was kidding... ...

EDIT: maybe he wasn't kidding... does it need to be said that there is no possible difference in perception from the vantage of a distant vehicle of two lights mounted 2" apart vs a possible 12" apart. My lights are mounted close together because that's where they fit best. I can control their angle, switch between modes, etc. with just one hand. I am not going to fool anyone into thinking I am a car by putting the lights at the ends of my bars! The size and color of the lights are completely wrong for one thing, even though lots of cars are running HID lights these days. I think drivers can tell the difference between 2" diam.lights mounted 14" apart from 7" diam. lights that are 48" apart? No?
