INTRODUCTION
The glareshield warning lights for the Lear 20 series provide a warning for airplane equip-
ment malfunctions, an indication of an unsafe operation condition requiring immediate
attention, or an indication that a system is in operation. Airplanes prior to 24-156 and
25-010 did not originally have glareshield warning lights, but they may have been
retrofitted.
GENERAL
The warning system consists of three hori-
zontal rows of annunciator lights colored red,
amber, and green (see “Annunciator Panel”
section), which alert the pilots to various mal-
functions or switch positions. The lights are
located on the center portion of the glareshield
just above the engine gages. These lights are
referred to as the glareshield warning lights.
Provision is made to test all warning system
lights with a switch located just beneath the
glareshield lights panel.
Other annunciator lights are located on the
instrument panel, center pedestal, or thrust re-
verser control panel, which are not part of the
master warning system. These lights function
independently as system advisory annunciators.
