Auxiliary Roof-Mounted Lamp; Exterior Cargo Lamps - GMC Sierra Limited 1500 2019 Owner's Manual

180 Lighting
Some localities have laws that
require the headlamps to be on with
the fog lamps.
Auxiliary
Roof-Mounted Lamp
If equipped, this button includes
wiring provisions for a dealer or a
qualified service center to install an
auxiliary roof lamp.
This button is on the overhead
console.
When the wiring is connected to an

auxiliary roof-mounted lamp,

pressing the bottom of the button
will activate the lamp and illuminate
an indicator light at the bottom of
this button. Pressing the top of the
button will turn off the roof-mounted
lamp and indicator.
The emergency roof lamp circuit is
fused at 30 amps, so the total
current draw of the attached lamps
should be less than this value. The
attachment points for the roof lamp
circuits are two blunt cut wires
above the overhead console: a dark
green with blue stripe switched
power wire and a black ground wire.
For information on roof-mounted
emergency lamp installation, see
www.gmupfitter.com or contact your
dealer.
If the vehicle has this button, the
vehicle may have the snow plow
prep package. See Add-On
Electrical Equipment 0 323.

Exterior Cargo Lamps

The cargo lamp provides more light
in the cargo area or on the sides of
the vehicle, if needed. The lamps
inside the pickup box and/or on the
outside mirrors also turn on,
if equipped.
