There is. If you can get Busch & Muller gear at a reasonable price, Europeans currently consider the B&M Toplight Line Plus to be the state of the art rear lamp. As a bonus it is, by BUMM and European standards anyway, pretty cheap, though overpriced for what is essentially a piece of cheap plastic (made with hightech optics, true) with some electronics. There are battery and hub dynamo models, and it has a standlight (keeps shining for a period even if you stop the bike). It is the first reasonably priced lamp that is superior to Cateye TL-LD1100, the longtime champion. It's only downside is that it doesn't blink, because that is forbidden by German law. You can see mine photographed in daylight as a daylight running lamps at

This is the BUMM English page for the Line Plus for dynamo operation

and here is the battery version

Senso means the lamp switches itself on when it grows dark. Maybe you want it if you use battery lamps, but if you use dynamo lamps, these BUMM lamps lend themselves well to be run as daylight running lamps, so you don't need the Senso versions. However, the senso version is so popular, there is usually no saving, so I've always bought the Senso version; it works. I bought mine from XXCycle in France, who ship to the States. You can start from this English page:

There's a fellow in the States who imports BUMM lamps, but his prices are a bit fancy, though his delivery may be cheaper; you can find Peter White at

Hope this helps.
