LED High Beam and Low Beam Headlight Install on 5th Gen 4Runner (Step by Step Guide)

This a complete plug-n-play install. The only issue and toughest part of this install is the driver side. In a previous post for installing the low beam headlight bulbs, we mentioned that the driver side was tight. And, it is.

If you want a little more room to work on the driver side, I recommend removing the battery. Although this is not needed, it will make installing the new low beams a little easier. The low beam and high beam bulbs have these little tabs that need to be pressed in and twisted (locked) into place. These plastic tabs are pretty awkward to plug and twist into place if you have a tight space to work with. So, removing the battery does help.

The high beam bulbs are much easier to install than the low beams. There is much more room to work with on the high beams, so the process goes much quicker than the low beams.

The Bulbs

The high beam bulbs will wow you for sure. They are BRIGHT!! Going from the stock 4Runner halogens to these LED bulbs will knock your socks off. It is pretty impressive. These lights kick ass.

For the low beam lights, they are brighter but not by much. They didn’t “wow me” like the high beams. They are a brighter white/blue color as opposed to the yellow/ orange color of the halogens which does make driving more visible.

But, you also have an option with HIDs for your low beams. If you are not familiar with HIDs, you should check out a few of the posts we have written on them. HIDs are brighter, stronger and produce better light output than an LED. But they also have their own set of drawbacks.

Do your research before buying a set of bulbs as everyone’s needs are going to be a little different.

Step #1 – Remove Dust Caps

4Runner LED Headlight Install - Remove Dust Caps

Start on the passenger side. You have more room to work on the passenger side. This will get you familiar with the process before moving onto the tighter space on the driver side.

Removing the dust caps can be done by hand or using a flathead screwdriver, gently pushing down on one of the tabs. You need to unscrew them just a bit and then they pop out of the housing.

Step #2 – Twist light Bulb and Pop Lose

With the dust caps off, you can access the bulb housing. Gently twist the bulb out of its housing. This will pop the bulb lose of the tabs that are holding it in place.

Step #3 – Pull Out OEM Light Bulb

With a bit of wiggle, the bulb will pop out on its own. Pull out the bulb and the wiring to give yourself some room to work with.

Step #4 – Disconnect Bulb

Disconnect the bulb by pressing down on the bracket tab. This will release the bulb free of the connection.

Step #5 – Preparing Light Bulbs

Prepare your first install on the passenger side by setting your lights out.

Step #6 – Plug in Light Bulbs

This install is plug-n-play. All you need to do is plug them in.

Step #7 – Testing Bulbs

4Runner LED Headlight Install - Testing LED Lights

Always test your lights to make sure you didn’t get a bad batch of diodes. It is common from time to time to have a bad light. If you install both sides, shut the hood and realize one does not work, you are going to be pretty irritated. So testing your new lights is a good step.

Step #8 – Notice Different Size Tabs

4Runner LED Headlight Install - Notice Different Size Tabs on LED Bulbs

Note that there are different size tabs for fitting your bulbs. There are two tabs that are large and one tab that is small. Your OEM headlights have the same tabs. They are designed to go in one way and only that one way. Just make a mental note of where these tabs are, line it up and pop the new bulbs. Twist and turn them into place, you are all set!

Step #9 – Place Bulb in Housing

4Runner LED Headlight Install - Place LED Bulb in Housing

Place your bulbs into place, line up your tabs in the correct position, and twist. You will need to put some serious pressure on the back of the bulb to press them in. The Cougar Motor bulbs come with a hefty backing, so use this to your advantage. Press in hard and turn at the same time, locking your new bulbs into place.

Step #10 – Optional Zip-Tie

4Runner LED Headlight Install - Optional Zip-tie

This is not a mandatory step and if you do not have zip-ties, you will be fine. But, zip-ties are an important step of every install on our 4Runner. The zip-tie helps keep the wiring a bit more organized in the low beam housing.

Also, you don’t need to zip-tie the wires together very tight. You can leave them somewhat tight. If you ever go to swap out your LEDs with an HID retrofit kit or new 4Runner LED lights, you can simply cut the wire with more room, not risking any damage on the current lights.

Step #11 – Bundle Wire and Place in Housing

4Runner LED Headlight Install - Bundle Wire and Place in Housing

Bundle your wires together as clean and as tight as possible and place them to the side of your LED bulb and into the housing, completely.

Step #12 – Screw on Dust Cap

Screw back on your dust cap and call the passenger side a day. Test your lights again, just to make sure everything is working inside the housing.

DRIVER SIDE INSTALL Step #1 – Remove Dust Cap with Flathead

(Remove Battery Optional)

4Runner LED Headlight Install Driver Side - Remove Dust Cap Screw Driver

The driver side is a bit more tricky only because the area you have to work with is so tight. If you have big hands, you will absolutely want to remove the battery. I have normal sized hands and it was tight. Removing the battery will give you so much more room to work with and when you go to tighten down the new LED bulbs, you have cuts and scratches all over your hand.

I struggled with screwing in the driver side bulb for about 20 minutes. Finally, I gave up and removed the battery. After I removed the battery, I screwed the new LED bulb right in.

For removing the driver side dust cap, you can do this with a flathead by gently pressing down or using your hands. Again, if you take the battery out, you can do it with your hands, no problem. But, with the battery still in place, using a flathead makes it pretty easy.

Step #2 –  Access without Battery Makes it Easier

You can see the difference from the shot above to this shot. It is much more open without the battery. The light on the left if your new LED low beam and the light on the right is your OEM high beams.

Just repeat the same steps from the passenger side on the driver side and you should be good to go. While you are on this side, you might as well install the new LED high beams.

Step #3 – Twist Bulb Housing Loose

Great pictures…you can really see the difference. After using them tonight in the pitch black winter, I’m going to consider Xenon Depot’s lights VERY soon. After Xmas for sure. Good call and a great experiment. Love the article.

Brennan. Thank you for writing up this article. We just finished installing our cougar motor LED lights and they rock. We ordered both the high beams and the low beams and love how much whiter the headlights look than the stock yellow orange color. Thank again and great website. Keep it going!

In my opinion you should take this down, the lights suck like you end up saying in a later headlight install. I never got the first one installed fell apart in my hand from too much pressure trying to shove it in… Of coarse then i read the later install using XenonDepot…..

Great site and videos, I had a question on this install. Last night I installed these on my 2018 4runner and the lights worked perfectly and I only installed the low beams. After checking everything is working along with the brights but drl are not coming on. Did I miss a step?

This is tremendously helpful! Replacing the headlights with simple upgraded aftermarket halogens and the LED flog light install were the best hour I’ve spent in a while. Awesome!

Is it just me seeing the factory halogen lights lighting up more space? Yes, the color of the LED are better, but the range of lighting is narrower. Low beam LED is worthless.

The reason the low beam is so difficult to install is because the cooling fins on the LED light housing hit and interfere with the headlight assembly on the 4R. If you grind down the fins on the LED housing where they contact the 4R housing it will make clearance so they will drop right in. That’s what I did. No harm the the light either.

On the 2017 the headlights seem to be perpedicular to the projector direction. Is there a specific degree I need to turn the Xenon Pro LED to get the optimum output? The trial and error looks like it can take asustantial time.

Thanks for the instructions. They were perfect for my install. The only difference for me was the LEDs themselves. I found these on Amazon and given the price, reviews and the built-in driver I went with them.

Basically a Lasfit kit with both H11 and 9005 sets.
So far so good in terms of light output. Time will tell how they last. It was a tight fit to get the led bulb in the socket. But I had no issues with Daytime lights.

Thanks again for the great write up!

I also put these lasfit LEDs on my 18 absolutely love them. DRL works little flickering but probably cause of the lower power being used doesnt bother me though they still work. Got the highs, lows, and fogs for about $90 on Amazon a steal if u ask me.

Awesome instructional, thanks!! Just wanted to reiterate a tip that Greg talked about above. Go buy a flat bastard (metal file) and shave back the metal housing on the low beam bulb where it rubs up against the housing of the low beam light on the 4R. Made it sooooo much easier. Didn’t need to remove the battery because of this. Thanks!

Has anyone heard any feed back on the company diode dynamics?
They seem well made. Any comment vs xenon depot LEDs.

Thanks for this write up! Any suggestions for installing the cougar motor bulbs (low beam) on a 2013 Gen 5? No dust cap but even less room to work with on getting the bulb to slide in. Hoping I don’t have to remove the headlight assembly but thinking I may. Any thoughts?

Just wondering if you ran into any issues with install. My high beams went in easy but the low beams are proving a little more difficult…. as in the won’t spin at all to lock into place. Advice?

Thanks for a very well done guide! A few questions: 1. It’s been 11 months since you posted this guide. How are the lights working after all this time? 2. Is there any brightness difference between the bulbs? Was looking at the Morimoto 2Stroke 2.0 LEDs for both low & high beams. Thoughts?

I am having trouble installing the lights. Seems like the fitting for the lights is too big for the plug in. Or am I missing a step?

Just installed them on my new 2019 and they look great. Obviously these things get pretty hot after just a few minutes being on, do you know of any issues with wiring, hosing, etc. that could be caused due to the heat from these?
