One thing I've seen in NYC that I think is cute and clever is having two headlights on the sides of a very wide Wald front basket. Having two widely spaced headlights gives one a feel of perspective, since as the vehicle approaches, you can estimate the approaching speed.
That's a really great idea. I've also been looking at light placement, though, and wondering whether it might make more sense to mount lights to the fork.
