    I use my bike to get around uptown. It is a townie. I tend to forget to turn off the lights when I return at night, coming from the dark to a lighted driveway.

    I'd like either lights with some kind of motion sensor that turns them off after X amount if time not moving or in a lit area, or, preferably, a hub generator.

    I don't know why someone doesn't make the first option.

    The second option is crazy expensive. I keep getting quotes around $200. When looking at Amazon.de I see whole bikes equipped with them at €200, which is about $260.

    Is there anywhere in San Diego I can get one at a reasonable price?

    Reel Light is a much lighter and more affordable option than more expensive dynamo hubs.

    Very interesting lights. The Reel Light website lists QBP as US distributor. Should be able to order from just about any bike shop.

    Yes, hub generators are pricey, but you don't need the expensive Schmidt models from Germany for an everyday commuter bike. I get along just fine with my Shimano hub for my 30 minute commute. Still more that the Reel Light, but you can say goodbye to purchasing and having to dispose of batteries, so you get some of that back over time.

    This one is $110:

    The cost of the hub isn't the issue, it's the cost of the new spokes and labor in installing it.

    The reelight is something you can bang together yourself a-la instructibles.com and it may be good for being seen but not illuminating the path ahead.

    I may just have to learn to install spokes.

    If you already have the generator, spokes, and rim, there are people on this board that can teach you how to build a wheel for no more than a beer or two on a free afternoon.

    My favorite (professional) wheelbuilder in town is Sheamus, who's bike shop is on 16th and E St downtown. If you have all the materials, ask him for a quote on just stringing. You can probably figure out the wiring yourself afterwards.

    I usually refer people over to Marzhel https://www.facebook.com/marzhel.pinto?fref=ts
    He lives in the SoBay area, and works at State and NoPk Bikes as well. Sheamus is a good guy too. With a number of people up to the task in town, it comes down to what part of town is most convenient to you.

    I would suggest coming to the velodrome tonight (join some of us for dimmer if you have time https://www.facebook.com/events/437106576405264/ ) People who lace track bikes and other fixed gears, have to have their act together. Because of the reverse torque, too tight, and you're snapping spokes. Too loose, and your rim will wobble so bad that you'll be riding on tacos in no time.

    I'm very happy with the wheel Ryan built for me.at Terra Rhythm in OB.
