Looking for ideas on how to mount a 30 inch single row light bar in the roof rack of my truck. Would it be a good idea to drill thru the cross beam in the back? want it to be a brighter cargo light/back up light.

Also looking for ideas on how to run the wire down the cab of the truck. If anyone has done this and has pics, i would appreciate it.

I had toyed with the rear light bar idea. Mounting you could use the inside rear foot pads of the roof rack, but would need to either drill into those or integrate using the existing holes and fab up a mount like this one I found this would be a PITA to deal with so opted for flush mounted Rigid Dually's in the rear bumper.

Many folks have lights mounted below the bumper and some I've seen on the roof rack.

Also, depending on if garage kept and clearance, could integrate something like this cross bar, but it may be set too far back due to how our rear roof rack caps are seated.

I've combed through FJ forums for supplemental roof rack ideas - check out Moab Junky on this site. I'm working on getting some brackets fabbed up locally using the roof rack foot pads for a forward 40" light bar - also looking at side lights as well.

If you don"t want to drill holes in the roof rack use
tube clamps.All sorts of shapes and sizes
that could easily be modified to accept light brackets. On page 27 I of my build thread I attached the gps to the cage with a tube clamp.Same way mounting the fuel regulator and filter on the hoop brace. I made mine but I am sure you can find an after market clamp that will work.Although not very clean,hose clamps work also.Examples on page 6 0f my build thread.The 4" dia.abs tube in the photo(tire tools holder) is held on with hose clamps.

Thanks for the info. I don't want to have to fab anything up so in my case only a few ideas would work. I have no problem driving the last cross beam in the roof rack. I think that xterra bar might sit too far back and not give me the look i want.

I may end up getting flush rigid cubes in the bumper too, i just like the look of there new radiance bar with the backlighting and figured a red one would look great at night. The truck is garage kept and i would be mounting the bar in the underside of the rack, right above the third break light and not on top.

just need to figure out how to run the wires clean

If you are willing to drill a hole in the roof... This is how I installed my amateur radio antenna (motorized mount for parking garages) to the roof rack and routed the wiring. While at it, I ran the power for a light bar to come later.

Although my install is up front, it should work the same for a rear facing light bar. The factory roof rack uses plastic brackets, so I would be reluctant to have anything heavy or large supported by them. If you can use the existing bolts (to the metal roof) for your light, it would be more solid...

Drilled a hole (using a step drill) under one of the roof rack mounting feet...



Used a filled grommet (like Ziebart uses to plug holes after an undercoating) in the hole to run the wires through and protect the the wiring...



Filled the grommet with caulk to keep the weather out...



Put everything back in place with wire loom and a drip loop. No leaks or issues...

Gotcha on the aesthetics (My 40" light bar is an amber radiance bar) and can't wait to get it installed.

The flush bumper mounted Diffused Dually's work great for me and I'm the same wanting everything installed cleanly. I plan on getting my dad the rectangular style vs. my square style for his Tacoma.

I plan on running this quick disconnect harness(not cheap) in case you need to replace/service your lighting. It is often used on police and emergency vehicles. Either way, you'll most likely still need to drill in the roof; I've seen posts where folks have drilled under the roof rack footpads to minimize potential water intrusion as well as plenty of marine connectors to choose from too.

Nicely done - your stuff always very clean. Plan on doing the same for my front bar.

i have no plans on drilling the roof, at least not yet but you did give me some ideas.

Thanks a lot!
