Yeah, aesthetics aside, the best thing you could do to that mount is put some heat-shrink tubing or closed-cell foam on it so that if you end up face- or crotch-planting on it during some emergency maneuver, it doesn't cause serious injury. At the very least you should flip it around so the bolt is pointing forward and the smooth part is facing you while riding.

On-topic, should be a fine "be seen" light.
