Abstract
A glass support bead through which inlead wires extend in a miniature type of flash lamp is shaped to have sloping sides and a narrow ridge at the top extending from one to the other of the inlead wires, so that any unburned metal foil in a flashed lamp is not likely to accumulate on the top of the bead so as to cause an electrical short between the inlead wires.
