Complete LED Light Bulb Swap and Replacement on 5th Gen 4Runner

Jump To: 

If you are looking to swap your stock lights out for LEDs on your 5th Gen 4Runner, you will find the light bulb numbers on this page. This is an overview of the interior and exterior bulbs.

If you are looking for suggestions on headlights and fog lights, go to that page. This page will give you the exact light bulb numbers you need to do a complete LED light bulb swap. I didn’t realize how many lights we actually had until we jumped into this post.

I mapped these numbers to a 2014 4Runner. You may want to map your own year 4Runner but nothing has changed on the 2014-current models of the 4Runner in terms of interior/ exterior lighting, so you should be fine. Anyway, this is just a good reference point for light bulb numbers.

All of the stock 4Runner lights on the outside are pretty weak. We are going to start with the license plate bulbs (168) and the move to the side marker light bulbs (168).

After we have those installed, we will then get the turn signal light bulbs in the rear (7443) and front (7444NA). Lastly, we will end with the parking light bulb which is also bulb number 7444NA.

We will be doing a follow up on this post with a step by step install on all bulbs. This will include every exterior light that is possible to swap out.

  • Map Lights (top front lights): (x2 bulbs)
  • Interior Door Courtesy: (x4 bulbs)
  • Dome: (x1 bulbs)
  • Rear Door aks Rear Hatch: (x2 bulbs)
  • Vanity aka Visor Light: (x2 bulbs)

Total interior lights you need to buy:

For the Interior lights, you can upgrade and replace all of the incandescent bulbs to bright white LEDs. There are many super bright LEDs out there.

The two lights that are common to swap out with are the Philips LEDs and DDM festoons. Many guys have tested hundreds of lights in their 4Runner interior and these seem to be the best combination of lights for an interior led light kit.

Most of the light bulbs (168) push about 280 lumens. The 168 bulb is your door courtesy lights, visor/ vanity lights, and map lights. The DE3175 light is for your dome light and the rear hatch light. The DE3175 pushes about 300 lumens.

Total interior lights:

  • DE3175 (x3)
  • 168 (x8)

Total exterior lights:

  • 168 Bulbs (x6)
  • 912/921 Bulbs (x2)
  • 7444NA (x2)
  • 7440A (x2)


  • DE3175 (x3)
  • 168 (x14)
  • 912/921 Bulbs (x2)
  • 7444NA (x2)
  • 7440A (x2)

This post took me a couple weeks to write-up. There is no exact information on the light bulb numbers, interior or exterior.

There are a few sections on the forum that have some good insight, but no real list of bulbs. You can also find everything in your owners manual but who likes flipping through 500 pages of paper.

Hopefully, this list helps you! If someone out there has some light to bring to the table, no pun intended, please leave a comment below.
