Preparing the Mounting Surface
HEAVY OBJECT
To avoid personal injury and damage to the lightbar, an assistant should help handle
the lightbar assembly.
IMPORTANT: Planallcableroutingbeforecompletingtheinstallation.
1. Placethelightbaronthevehicleroofattheselectedlocation.Thelightbarshouldtypicallybe
installedapproximatelyoverthedriver’shead.
2. Adjustbothmountingbracketassembliesinoroutuntiltherubbermountingpadsrestnear
theedgeoftheroof,orgutter,wheretheroofismostrigid.
3. Centerthelightbarassemblysothattheendoftheassemblyandedgeoftheroofare
equidistantoneachsideofthevehicle(Figure 3onpage4).Tightenthe3/8-16hexnuts
(twooneachmountingbracket)installedinPreparing the Lightbar for Installation,steps2
and3.

4Vista Model XAPK-SC, -SD or XPK-SC, -SD Permanent Mount Kit
4. Tomaximizeaerodynamicefciencyandhigh-speedstability,itisrecommendthatthe
lightbarbemountedwithaone-inchorgreatergapbetweenthebottomedgeofthelightbar
andtheroof.Onahigh-crownedroof,oneinchmaynotbepossible.Inthiscase,adjustthe
lightbarashighaspossible.Adjustthemountingfeetonthemountingbracketasneeded.
5. Checktoensurethatthelightbarislevelfront-to-back.Ifitisnot,adjustthelevelby
rotatingthelightbarinthemountingbracketslots.Tightenalleight5/16Torxheadboltsthat
fastenthemountingfeettothemountingbrackets.
6. Usingthemountingbracketsasatemplate,scribetwodrill-positionmarksoneachsideof
thelightbar.
7. Removethelightbarassemblyfromthevehicleroof.Toavoidmarringtheplasticdomes,
placethelightbaronsoftragsorcardboard.
8. Turnthelightbarassemblyoversothatthebottomoftheassemblyfacesup.Securethe
mountingassemblytothelightbarusingtheeight#10hexheadthread-formingscrews.
9. Tightenthe3/8-16hexnuts(twooneachmountingbracket)installedinstep7ofPreparing
the Lightbar for Installation.Placethelightbarassemblyonthevehicleroofinthepreviously
determinedposition.

edges should be smoothed. All wire routings going through drilled holes should be
protected by a grommet or convoluted/split loom tubing.
1. Beforedrilling,movethelightbarassemblyoutoftheway.Drillfour1/2-inchdiameterholes
atthescribeddrillpositionmarks.
2. InsertatoggleboltineachofthefourdrilledholesandsealtheholeswithRTV.Slidetwo
rubbermountingpadsovereachboltasyouinsertit(Figure 4onpage5).Usecautionto
avoiddroppingtheboltsthroughtheholesbeforetherubbermountingpadsareinstalled.
3. Placethemountingbracketsdownovertheendsofthetoggleboltsandsecurethemwiththe
jamnuts(Figure 4 on page 5).Tightenthejamnutjustuntiltherubberpadbeginstobulge.
Donotexceedatorqueof60in-lb.
