Lamp Out Indicator: Description and Operation
1982---87 THUNDERBIRD, COUGAR & XR-7; 1982 LINCOLN CONTINENTAL; 1983---87 LTD & MARQUIS
The lamp-out warning system monitors low-beam headlamps, tail lamps and brake lamps. The system consists of a warning module, a wiring harness
and a set of three indicator lamps located on the upper tier of the instrument panel. The wiring harness used with the system uses special resistance wire
to ensure proper system operation. To prevent malfunctioning of the system, the lengths of these wires should never be altered. The warning module
contains a printed circuit board and logic circuitry. Normal operating voltage is 10---15 volts, however the unit will withstand up to 24 volts for a period
of 15 minutes. The lamp-out warning system operates when the ignition is in ACC or RUN position. If one or more low beam lamps are burned out
when headlamps are energized in low beam mode, the low beam Out indicator will illuminate. The tail lamp Out indicator will illuminate when running
lamps are energized and one or more tail lamps are burned out. The brake lamp Out indicator will light when brake lights are energized and one or more
brake lamps are burned out. When ignition key is in START position, all three warning lights should illuminate.
