That is an LED lamp, and quite a seriously bright one, too - it's an Iq Cyo that puts out 60 Lux (pictures of the beams here) and is driven off the dynohub.

I just have rather funny geometry round the front fork & brakes, I think. Something to think about as and when it's new bike time :)

Ah, I see. I couldn't tell that from the photo. That's bright! Bikes are so complex these days! Pat rides a Cannondale mountain bike with street tires. (He has an arthritis problem, so he needs something that keeps him slightly more upright than a regular street bike.) It's constantly amazing to me how technical all the structures have gotten.

Not like the bikes I rode as a kid at all!

Modern hub dynamos and LED lamps are pretty amazing - they push out a lot of light, and as the rider I don't notice any rolling resistance from the hub dynamo at all.
