While doing some light research (pardon the pun there!), I came across some really neat LED lights that have their own dynamo built in. They are called Magnic Lights. I've got an email into the sales division of their company to find out if/how they would mount to a Catrike Road. I'm seriously thinking about getting at least the red tail light for the bike - that way there is no dependence on battery in case my current ones go dead. They are listed at $71.01 (excluding VAT). Don't ask me why they added a penny onto the end instead of making it $71, or $70.99. And I'm not sure if that's USD or another denomination. You can get a complete set (2 front lights and 1 rear) for $206.47. I'll get more information as quickly as I can. Once I get it in, I'll do some video of it in comparison to some of the other lights we have on hand. I'm waiting till I can get enough different lights to do a really good comparison.
