I really think you need an integrated full set of lights, so that, for instance, when left is indicated, the right light is on steady and the left is blinking at a normal rate for a turn signal (about 1.5 hz, maybe a little faster). If you just have one light blinking, then it's going to be perceived as a blinkie, not as a turn signal.

I'd be nervous about this anyway; if you use turn signals, will you stop using hand signals? It's such an odd thing to see on a bike, no matter how it's set up I'm afraid a lot of people won't realize what it is. Lots of people don't know what hand signals are either, but at least around here they at least think "that guy's doing something weird, I'm going to keep an eye on him."
