connected by three wire leads.

a. Replace the bulb by aligning the pins with the holes in the socket and seat the
bulb firmly.
Note: Use care and make sure that the leads are properly aligned when inserting the dual
filament bulb.
b. Wipe off any fingerprints from the bulb with a tissue and alcohol. Any oil left on
the bulb will permanently “smoke” the inside of the reflector.
c. Screw the socket back into the reflector assembly.
d. The socket can be adjusted in the spot reflector assembly.
(1). Turn the Vulcan on and shine it on a wall approximately 10 feet away.
(2). Adjust to the desired focus by screwing the socket inward towards the fully
seated position or outwards until the point where the socket O-ring starts to
leave the surrounding screw shell of the reflector.
Note: The focus should be attained somewhere between the two limits described (try 1/4
turn out from the fully seated position).
D. Place the reflector/lens assembly back into the Vulcan body.
E. Reassemble the Vulcan as shown in Section I.
