LASFIT LED Front/Rear Amber Turn Signals for the 5th Gen 4Runner – Plug and Play w/ built-in CANBUS (Resistor)

If you want a little extra lighting in your turn signals, LASFIT LEDs are the way to go! These LEDs are plug and play and require no resistors due to their built-in CANBUS. Typical LED turn signals will require you to tap into a cable and add a resistor or you will sometimes receive errors or hyper-blinking will occur.

You can see one of those traditional LED turn signals with t-tap resistors here. This was done before any turn signal LEDs with built-in resistors were on the market.

LASFIT has 2 options for the front turn signals:

  • Amber
  • Switchbacks

Switchbacks will be white while always on and switch to amber when the turn signals are initiated. I chose to go with all amber lights because I was worried the white wouldn’t match my HID headlights and I also like the all amber look when I have the raptor lights on. The difference between the incandescent bulbs and the raptor lights always bugged me and I wanted something that matched better.

The fronts have 8 LEDs (2 for always-on and all 8 for turn signal or flashers), the rears have 6 and both have an output of 2400 lumens.

With that said, the LED turn signals are VERY BRIGHT and you will have no issues being noticed when you have your signals or flashers on. At the time of this article, I had been running these LEDs for about a month and had no issues with errors, overheating or hyper-blinking and would highly recommend these for an upgrade to your turn signals.

Front Turn Signal Step-By-Step Install

Tools and materials needed

Step 1. Turn Wheel Right/Left To Access Turn Signal Bulbs

LASFIT LED Front and Rear Amber Turn Signals Step-By-Step Install & Product Overview For the 5th Gen 4Runner

Turn the wheel all the way to the right or left depending on which side you are working on. Right if working on the driver side, left for the passenger side. This will give you some additional room to remove bolts and access to the turn signal bulbs.

Use the 10mm ratchet to remove the 4 bolts shown below. There are 3 bolts on the inside of the wheel well and one below.

Step 2. Remove Wheel Well Liner

Use the trim tool to remove the wheel well liner. If you place the trim tool in between the black clip and the actual bumper, it will help to get the liner away from the bumper.

Step 3. Remove Factory Turn Signal Bulb & Connector

Pull the liner back and towards the vehicle enough to be able to see up to the headlight.

Reach up and grab the bulb connector and turn it left and pull back. The bulb will come out by just pulling it straight out, there are no additional connections. I couldn’t get a great shot for this, but there is only one connector you will see.

Step 4. Install LASFIT Turn Signal Bulb & Attach Connector

Install LASFIT LED by pushing it straight into the connector. Test that the LED lights up before inserting it back into the headlight, if you have your keys handy just lock or unlock the truck to see that it lights up. These LEDs are polarity specific and will only work one way. If the LED does not light up, just remove it and rotate it around and test again.

Reinstall the LED and connector to the headlight.

Replace the wheel well liner and be sure that the black clips are overlapping the bumper. Tighten the 4 bolts, these will not get very tight so go until they seem to be back in place. Repeat the above steps for the passenger side.

LASFIT LEDs vs. OEM Turn Signal Bulb

Rear Turn Signal Step-By-Step Install

On to the rear turn signals! 

On this, you will need to remove the taillights since the LASFIT LEDs are longer than the bulb, the connector does not provide much slack and it’s nearly impossible to get these in with the taillights attached.

Step 5. Open Rear Hatch & Remove Access Panels (x2)

Open the rear hatch and locate the access panel nearest to the hatch opening.

Use the trim tool to remove the 2 access panels. There is a small indentation that you can insert the trim tool in to remove. Press in and pull out.

Step 6. Remove All 3 Connections To Taillight

There are 3 connections on the taillight that you will either need to twist and remove or press down on the tab and pull out.

Remove each of these so you don’t have any wires to deal with when removing the taillight. You will also remove the 2 10mm nuts using a deep socket and ratchet.

Be careful when removing these and don’t drop them as I learned this the hard way.

Step 7. Remove Taillight (Use Trim Tool, If Needed)

Remove the taillight. This takes a little effort as there isn’t a good place to grab hold of the taillight. I found that using one of the trim tools and moving the taillight back and forth let it release.

Just be patient when doing this and the taillight will make a few pops that sound like something is breaking before it comes loose.

Step 8. Remove Bulb Connector & Install LASFIT LEDs

Remove the bulb from the connector and replace it with the LASFIT LED. Be sure to, again, test the LED before installing it to the taillight. If this is not working due to reverse polarity, then rotate it and reinstall.

Note: I used needle nose pliers on this step to get the LED into the socket; it’s a little tricky since there isn’t much slack. And be sure not to drop the LED into the taillight.

Step 9. Reinstall Taillight, 3 Connectors & Tighten Bolts

Push the taillight back in; you will hear a couple pops as it reconnects. Then, reinstall the 3 connections and tighten up the bolts. Repeat steps for the other side and you’re all done!

These new turn signals don’t require tap into your factory wiring harness. If you are looking for upgraded turn signals or switchback LEDs, this is absolutely the way to go. This is about as plug and play as it gets. Highly recommend these.

Finally getting around to doing this mod, quick question though. Did you get the standard bulbs or the CK bulbs?

Hey Trevor, the 4runner uses the standard socket.

Hello folks.

I installed these on my 2020 4R. Had to remove the rear light assembly on both sides for proper installation. Installed the ones on the front left and everything went great. No hyperflashing. Once I installed the one on the front right, it started to hyperflash. Didn’t give it any thought left it as is. Couple of days later, it stopped hyperflashing. Since it had stopped, I went on and turned on the hazard lights for 5 minutes; it began to hyperflash again. Most likely the front right bulb is not functioning well. Lasfit has a 2 year warranty on these led lights and their customer service is good. Now, to take that one out and hope the replacement works flawlessly as the other three.

Great to hear that their support is sending you out a new one. Hopefully they work for you after the new one is in. Thanks for sharing!

Bought the fronts and rears for my 2018 TRD Off-Road and installed today. Thanks so much for the helpful article. Love the lights and they’re really bright. Bought the ones with the white front running lights and with the stock headlights it looks nice but if I had to do it again I’d probably get the orange ones. I also accidentally dropped one of the tail lights into the housing (as you mentioned you had in the article as well). Was def a 15 minute diversion but if you’re thinking about installing def be mindful of not dropping it in lol.

Hey Lee,

Glad the article was helpful for you! Fortunately I didn’t drop mine in the taillight but came very close. Wish those connectors were a little longer. Thanks for the post!

Hey Rico,

Check Lasfit.com for fitment. These might not fit but they may have another version that will.

May be a weird question but how will these hold up if you leave them on as your running lights?

Hey Trevor,

I’ve been running these for a couple months now and haven’t had any issues. They are always on while driving at night and I haven’t noticed anything weird with hyper flashing or overheating.

Maybe this is a silly question but does this work for a 2020 4runner? Also does the 2020 require the same number of bulbs? Amazon keeps says these don’t fit 2020 4runner. Just want to make sure I get the right bulbs.

Hey Tylor, I checked LASFITs site and it looks like on the rear turn signals are compatible. Not sure what they did different with the fronts on the 2020s but I bet they have something available in the near future.

Thanks Kevin! Guess I will do the rear turn signals for now and wait on the front. Thanks for getting back to me.

Thanks for the info. Question, do the rear LEDs have a constant on? You mentioned the front has two LEDs on at all times, and six when blinking. Is that the same for the rear?

Hey Rob, the rears only come on when the turn signal or flashers are engaged and it’s all 6.

Kevin, Have you tested them out by running your flashers for an extended period of time to see if the bulbs heat up to much and start to hyper blink? I’ve seen (I believe an earlier model?) of these that after maybe 3 minutes would start to hyper blink. Just wanted to check with your experience on these. Thanks!

Hey Collin, I just tested and ran the flashers for 5 mins with no hyper blink.

After waiting in the chic fila parking lot for a few minutes I think mine are getting too hot. And the duration, not the frequency, of each flash becomes very short and requires a cool down period. I kind of want to change to another bulb

Why does the tail light assembly need to be pulled? The manual talks about replacing them without pulling the full unit

Hey Cory, since the LEDs are a lot longer than the bulbs and there isn’t much slack in the cable and connector is pretty hard to get the bulb in and connected back up. I was also afraid of dropping the bulb in the tail light. I tried a few different ways without pulling the tail light out but couldn’t get it to go.

I did it without pulling the full unit. I connected the bulb and then put it back. It is hard but you can do it.
