Rear lights that won't blind other cyclist and mount on a fender eyelet

I need a rear light to pair with my edelux II. I don't want to mount a light on my fender and I regularly use a carradice saddlebag, so seatpost light is a no-go.

I've seen some people mounting the Supernova rear light on rack/fender eyelets and that sounds great to me.

What are the options...
