Looking at my Ruby headlights today, they do not seem as bright as they used to be. The system is the original 6v positive earth set up - dynamo and cut-out - with the common 1950s 7" Lucas reflectors fitted and wiring altered to suit dipping of both. The battery and reflectors are in good condition, so I suspect the voltage reaching the bulbs is not what it was. I plan to have a go at cleaning up the various contacts on the live and earth side, but is there anything else that might help, please?
