THEORY OF OPERATION
High Intensity Discharge (HID) lighting describes a type of light source
producing light energy by means of an arc sustained within a gaseous
enclosure. This system is compromised of three (3) major components:
The bulb which contains the environment and houses the arc;
The starter (located on rear of bulb) which boosts the voltage from the
ballast to create the arc in the bulb; and
The ballast which provides high voltage to the starter.
Bulb
Major advantages of HID lighting are high color temperature producing a
brilliant white light and extended service life due to the absence of a wire
filament. These features lend themselves to applications requiring extended
use and severe conditions. HID provides the user several times the output
of incandescent or halogen lamps using the same levels of input energy.
GENERAL OPERATION:
The Speaker HID Light System is designed for heavy duty, long life
applications. When input power is introduced to the ballast system, an arc is
struck in the bulb between two contacts. Although HID offers extra long
service life, frequent re-striking (on/off) of the arc will shorten bulb life. Once
the arc is struck, it is preferable to leave the lamp on until it is no longer
needed. If a voltage disturbance extinguishes the arc, the system will shut
down to protect the lamp. If this occurs, you should remove power from the
lamp to allow a reset and then reapply power. Normal operation will resume.
If lamp operation is controlled by a switch or relay (not supplied), a minimum
contact rating of 20 Amp tungsten is recommended due to the current in-
rush at lamp start-up. Failure to adequately size will damage and/or shorten
the life of the switch.
Keeping the lens of the lamp clean of mud, paint, debris, etc. will also extend
the life and performance. Debris on the lens could cause damage due to
trapped heat. Damage of this type is not covered under the warranty and can
be prevented by simple cleaning with mild soap and water.
INSTALLATION
The HID lighting System consists of a lamp assembly with an internal ballast.
This assembly must be securely mounted to a stable operating surface.

WIRING REQUIREMENTS
The HID lighting System comes with approximately 30" of wire exiting the lamp
assembly. J.W. Speaker recommends keeping the wire length as short as
practical and running separate wires to each lamp to minimize voltage losses in
the wires. If this is not possible, heavier wire should be used to insure trouble-free
operation. An in-line fuse assembly is also included. J.W. Speaker strongly
recommends using this fuse to protect the vehicle wiring from damage.
From the power source to the lamp, the wire gauge will vary based on the
minimum/maximum voltages of the host equipment and the length of wire from
the power source to lamp. Most applications can use 18 gauge wire up to 15 feet
long. If your application requires greater distance, 16 gauge or heavier wire should
be used. For more specific recommendations, consult a qualified service
representative. Be sure the wire sheathing is correct for the operating
environment.
WIRE DIAGRAM:
The following wiring diagram is suggested for trouble free operation of the unit.
The HID system requires correct wiring polarity. The positive connection must
be made to the red wire and the negative to the black. Reversing the polarity will
not damage the unit but it will not operate.

The HID bulb contains gas under pressure and could shatter. Protect bulb
against abrasions, scratches and liquids. Do not touch the glass envelope.
Operate bulb only in a lamp assembly. Replace if damaged or cracked.
Wear eye protection when handling. Disconnect power before removing.
