Thanks for the infos. I have a few questions before going ahead:
- what tools would I need (I know nothing about 'tricity, but could find someone knowledgeable to help)?
- how big would 3/4 LiPo batteries be?
- how safe are they to use on a bike?
- how much power would a car horn use for this purpose, so that I have an idea of how often I'd have to recharge the batteries?
