Auxiliary Roof Mounted Lamp
If your vehicle has this feature, this button includes
wiring provisions for a dealer or a qualified
service center to install an auxiliary roof lamp.
This button is located
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 located above the overhead
console, a dark green switched power wire and a
black ground wire.
For further information on roof mount emergency
lamp installation, please visit the GM Upfitter
website at www.gmupfitters.com or contact
your dealer.
If your vehicle has this button, your vehicle may
have the snow plow prep package. For further
information see Adding a Snow Plow or Similar
Equipment on page 435.
