My dad has been having a bit of a clear out in my grandad's old shed, and has found an old lucas horn that's never been used. It looks much like this Lucas 7H Classic Car Horn LU/69152 Jaguar Bentley Aston Martin Jensen. | eBay and it's bloody loud. Anyone have any ideas on fitting it to the ebike, as it's quite large and heavy, and uses 12 volts as opposed to 36. I would hope not to need to use it very often of course but it seems a shame not to pt it on there!
