KC HiLiTES Gravity G4 Clear LED Fog Light Installation on 5th Gen 4Runner – What to Expect and are they for you?
After running a few different fog lights in the 5th Gen 4Runner housing, seeing the KC HiLiTES Gravity G4s was pretty cool. This might be the exact fog light you have been looking for, but it does come with a quirk, as of right now anyway.
We recently did a post on the top fog light options for the 5th Gen where we covered the Gravity G4s. After that post, we were anxious to get them installed and see what they were all about.
When looking at fog lights, you have a few options.
LED Bulbs
When it comes to LED bulbs, you can install one of the most common 5000-6000K fog light bulbs, or if you want to go with yellow or amber, the 3000K Xenon Depot yellow fog light bulbs, and of course, there are many others are out there.
LED Housing
If you look at full housing replacements, the first options that come to mind are the Morimoto XB LEDs and the Squadrons. The KC HiLiTES Gravity LED G4s are also a full housing replacement. Toyota also just started producing 4Runners with factory LED fog lights that you can buy.
Whether you choose to replace the bulbs or you go all in with new housings, an upgrade to the factory 4Runner fog lighting is a must.
Introducing the KC HiLiTES Gravity G4s
This specific fog light housing is direct plug and play upgrade for all 2012+ Tacomas and work for the 5th Gen 4Runner. These are a great LED fog light upgrade from your stock lights and are SAE street legal.
They are available in either clear or amber.

One of the use-case highlights of the Gravity G4s is that they are a great option between a bulb upgrade and a non-SAE street legal Baja Squadron.
When I mentioned “this might be the perfect fog light for you” I was serious. This is a great option for your 4Runner if you are looking for a step above a bulb but not overkill light output in a Squadron, for example.
Everyone wants different output and the Gravity G4s offer a pretty solid middle ground of lighting.
They are not going to throw an obnoxious amount of unneeded light output and they are going to be functional both on and offroad. If you are 90% on road and 10% off-road, and you want to run your fogs without getting flashed regularly, while still having a functional light offroad, the Gravity G4s are a pretty solid option.
I have covered this topic before but I genuinely feel like the Baja Squadrons, both sport and pros, were a little too much for everyday use.
I ran the Squadron Pro Clear Driving Lens for a little over a year and got flashed by oncoming traffic often. It wasn’t enough to make me swap them out right away but after a while, I did feel like “that guy”. Would I run the Squadrons again? Absolutely, they are just a bit overkill for everyday use.
The Gravity G4s are 866 Lumens Per light while the Squadron Sports are 3,150 per light.
Both are kick-ass products, its really on you to decide which one you want to run.
Gravity G4 Installation
The installation of fog lights on the 5th Gen is about as easy as it gets. This can be done on your lunch break at work in under an hour. There is something important to note about this specific install, though. The current Gravity G4 fog light is a universal housing so it works on 2006-2015 Toyota Tacoma, 10-19 Toyota 4runner, as well as Lexus and Scion Models.
The housing does fit on our 4Runner, it just uses one screw instead of two in order to hold the bracket in place, which is more than enough to hold. With the OEM housing, there are two tabs that first lock the housing into place and then two screws that lock the housing down as well. The Gravity G4 has those same two tabs but only one of the screws lined up. I was concerned at first but after a little wiggle, everything was just as solid as the OEM housing.

Step #3: Unplug & Remove Factory Lights or Current Lights
Step #4: Remove Factory Lights or Current Lights
Step #5: Prepare KC Gravity G4 Fog Light Housing
You have a couple options here. You can secure the KC fogs in place using one screw or file out the inside of the bracket tabs in order to fit both screws.
This is an updated portion of the article as I ran the fogs with one screw in place for over 6 months with zero problems. I had someone ask on Instagram if these fogs could be secured in place similar to the Morimoto Fog Lights using both screws.
You can fit the fogs in place using both screws. All you need to do is file out the inside holes on the bracket tabs with a circular file. See below.
Step #6: File Down Inside Bracket Tabs (optional)

It fits with both screws in place. All you need to do is file out the inside corners of the bracket tabs. Just make sure you have a small circular file and you are good to go.

After: KC Gravity G4 Fog Lights with XD HIDs
Installed these on my 2019 ORP, there were some modifications to get them to fit. The interior tabs of the lights were wider than stock (pictured). Since these tabs aren’t screwed in, I filed them down to fit the mounting points in the bumper.
The problem is there is a small gap between the lights and the bumper. It’s not noticeable unless it’s triggering your OCD. You can choose to not use the mounting points in the bumper and this will make the lights more flush. But they will be pointing out to the side more like ditch lights. Other than that, they work awesome and they look subtle.
Oh also another thing, on the passenger side there is a dust cover over the light that is kind of a pain in the butt to remove.
Excellent write up! Very easy to follow and the lights are beautiful. I went with the Amber Gravities and have no complaints.
Did you have any gaps around the new fog lights after install? I installed these last week and love the look, I just have a slight gap on the inside edge between the new fog light and the factory black fog light trim. I purchased the amber lights and they look great.
Scott, yeah there is a slight gap. But no aftermarket fog is going to be exact. They all seem to have a slight gap around the housing.
Every website I have reviewed says these won’t fit TRD. Or I have seen other sites saying I need a switch and relay. I hava a 2019 TRD Pro off-road premium. Do you know if these will fit?
late to the party here…did you get an answer…I installed mine 2 days ago…big gap and seem to focus most of the beam to the outside…like the ditch…KC website said they fit…happened to check amazon and there guide wouldnt sell them to me if I entered 4runner…thanks…I do not have a pro…just 2019 TRD…the factories have that slanted bezzle…we are tryoing to “mod” one before we send them back
I made it work with one screw. If you want to run both screws, you can make a few adjustments as needed which are very similar to the Morimoto XB LED fog lights.
Brenan great mod. Follow-up question. The Amazon link says these will not fit 5th gen (2019 4runner). Is that accurate or a mistake? Love the look and hoping these do fit.
How does it compare to Factory LED Fog Light?
Gabriel, if you are referring to the Factory LEDs found here, I don’t have any experience with those yet so hard to compare back to back. Judging by the images that Bryson put together on that post, those factory LEDs do look pretty impressive, especially with that sharp cutoff line. But, I didn’t see an actual lumen rating. That would give us at least some metric to compare against.
Thanks for the reply. Yes that the article I was referring. I’m looking to upgrade my fog light and trying to decide which are the best value for the money.
