I just got a Trelock LS950 the other day, and I'm pretty impressed by it so far. It's made in Germany, for the German market, so it meets the StVZO requirements with a shaped beam and all that, and there's no flashing mode (although supposedly there's an "export" version that does flash, but I didn't know of its existence until I saw it mentioned in the documentation included with my light).

Here's one of the reviews I read while researching it: Trelock Control Ion LS 950 Headlight | Road Bike Rider

It's about $200 on Amazon, but I got mine with two extra handlebar mounts ($40 each on Amazon) for about $118 including shipping from a German webstore. It took about two weeks to arrive.
