I have obtained a Raleigh Superbe bike in great condition. When I got it, the wires running down the fork to the dynohub had been cut. I spliced them, and connected the copper to copper, and silver to silver. Neither front or back lights are working. There is no rust inside the front or rear lights and no damage that I can see. Besides the possibility of both bulbs being out, anyone have any ideas what to do ? Where can one find replacement bulbs these days ? Ebay, Harris ? Thanks in advance for any suggestions.
