Original lamps for the Bond Mk C are now very diffiuclt to find. An alternative is the Wipac lamp used on the Scootacar, Bamby Mk11 and Peel P50. Stephen Boyd of the Scootacar register had a few nice ones for sale last weekend at the NMCR. Drop him an e-mail as I am sure he might be able to help. He might also have some of the steel bowls that go with the lamps.
