The German/European laws that these are designed for limit what can be done, although I don't know if the battery light conforms as the law wants dynamo lights, meaning no failure on the road.
In Germany the StVZO (the Road Traffic Licensing Regulations), require all bicycles over 11kg (23.2lbs) to have dynamo powered lighting. Which leaves battery powered lights as an option for road bikes. I kinda liked this Phillips model because it would cover both bases. It got better reviews than the dyno specific model and the batteries could be recharged in place via a dyno and adaptor.
Story of my life - most really neat things get discontinued because the average person doesn't think they're worth paying for.
