I was wondering if any one could recommend a Bottle generator. My apologies if this thread has already been addressed. What I wanted was a bottle generator and LED light set that would stay on while stopped, and if possible be able to switch to flashing on the front for day time use. I could probably build the capacitor circuit, but would like the off the shelf model if it exists. Don't want a dynamo hub at this point. This is more of a measure to get me to use lights during the day than anything. I'm not concerned about the extra drag so that isn't an issue. I also realize this is old technology but wondered if there was a latest and greatest version of this or maybe the Generator could be used with lights originally meant for dynamo hubs. Any advice would be highly appreciated, so thanks in advance.
