Installation Precautions

Preparing the Mounting Surface (Surface-Mount Model)
An installer-supplied fuse and fuse holder with a current capacity of at least 5 amperes are required. Also
required are an installer-supplied switch with a current capacity of at least 10 amperes, 18 AWG (minimum)
wire, and a grommet. Select appropriate mounting hardware for the application and plan all wire routing before
the installation.
To prepare the mounting surface:
1. Position the vehicle on a level surface. Select a relatively fl at mounting position for the light that provides
suffi cient rigidity to support it and prevents vibrations caused by the light when the vehicle is in motion.
2. Using the rubber gasket as a template, scribe mounting hole locations on the mounting surface. Place
the rubber gasket on the mounting surface over the mounting hole locations. Scribe a wire-routing hole
location on the mounting surface through the gasket.
3. Select the appropriate mounting hardware for the application. Drill holes at the three scribed mounting-
hole locations. Drill a hole at the scribed wire routing hole location. Remove all burrs and sharp edges.
NOTE: Group 3 permanent mount lights need an installer-supplied three M4 X 0.7 screws that are 16
mm long. Different mounting surfaces may require installer-supplied screws of a different length.
4. Install an installer-supplied grommet in the wire-routing hole.
AIRBAG DEPLOYMENT—Do not install equipment or route wiring in the
deployment path of an airbag. Failure to observe this warning will reduce the
effectiveness of the airbag or potentially dislodge the equipment, causing
serious injury or death.
ROOF SUPPORT STRUCTURE—There is a roof support member that spans the
distance between the driver and passenger side. DO NOT DRILL THROUGH THIS
MEMBER! Adjust any hole locations until the holes can be drilled without going
through this member. Failure to follow this warning will weaken the roof of the
vehicle and may lead to an increased chance of bodily injury or death in a roll-
over accident.
BATTERY EXPLOSION—To avoid a battery explosion, always disconnect the
negative battery cable first and reconnect it last. Avoid a spark when connecting
near or to the battery. The gases produced by a battery can cause a battery
explosion that could result in vehicle damage and serious injury.
DRILLING PRECAUTIONS—When drilling holes, check the area into which you
are drilling to be sure you do not damage vehicle components. All drilled holes
should be deburred and all sharp edges should be smoothed. All wire routings
going through drilled holes should be protected by a grommet or convolute/split
loom tubing.
