Hitachi CHROMASTER 5160 Instruction Manual page 571

Attach a new xenon lamp in place.
Attach the cathode lead plate to the threaded part of
the cathode, and secure the lead plate with the
cathode nut (Fig. 5-6). Mount the lamp so that the
protrusion on the bulb faces the instrument front panel
(Fig. 5-7).
Be careful not to touch the lamp bulb. Note that a thin
metal wire is attached near the center of the bulb,
which facilitates ignition of the lamp. Take care not to
break this wire when handling the lamp.
Also, if the thin metal wire is not located on the side of
the lamp having the small protrusion, slide the wire so
it is properly positioned there.
