LED Dome Light Swap and Light Replacement on 5th Gen 4Runner

When you unlock your 4Runner, the dome light, the puddle (side mirror) lights, and the map lights turn on. This gives you a good sense of perspective. It sounds lame but it really does. After unlocking your 4R and seeing those two sets of lights turn on, you suddenly know where everything is.

The dome light is an essential part of everyday life. You will find out pretty quickly when you go to turn on the dome light and it barely lights up the back seat. Adding brighter lights is key for your night experience.

The dome light covers the center of your cabin. Having a high-quality bulb helps to cover areas of your 4R, where the stock lights don’t reach.

If you notice your dome lights going dim or any other interior lights, you should probably look at an LED swap. If you are looking for a little more punch from your factory lights, swap your stock ones out with LEDs. After you throw in LEDs, you will be pretty excited about the color and the newfound brightness.

Dome Light Bulb Replacement (Festoon Bulb Number)

4Runner Dome Light Bulbs (Festoon DE3175)


If you are looking to buy an interior light bulb kit, this should cover ever major light.

  • 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:

Step #1: Pop light bulb cover

Start by grabbing your plastic pry tools. There are four tabs that hold the light cover in place. These tabs are facing both the front and the rear. The faceplate cover is on there incredibly tight, so take your time and wiggle the plastic pry tool into place. Once you have the plastic pry tool in place, just inside the housing, twist the pry tool and it should pop the first tab off. Repeat this step until your faceplate comes off.

Step #2: Release Metal Tab

To remove your actual bulb, you need to release the metal tab that holds the light into place. You can simply pull back on this tab with one figure to release the light bulb.

Step #3: Release Tab with Pry Tools if HOT

If the light housing is still hot, which mine was. You can use your plastic pry tools to release this tab. By using your plastic pry tools you wont burn your finger like I did. Either let your lights cool off or use one of your handy plastic tools.

Step #4: Remove OEM Bulb

Step #5: Swap in New Bulb

Step #6: Test New Light Bulb

Step #7: Replace Light Cover

Step #8: Press Firmly on Light Cover

The plastic faceplate cover is a little difficult to get back into place. Start with one end facing the front and press the other end into place. With your plastic pry tool, you can firmly press the entire plate upwards. This should snap everything into place.

Bulb Replacement Overview

This is a pretty straight-forward light bulb swap. The only thing you really need is your plastic pry tools. You can always use a flathead screwdriver but with a flathead, you might scratch up your light fixtures. You are much better off using a set of these plastic tools. They will come in handy for many other installs and mods.

I did this swap tonight and was disappointed. The new LED light did not seem any brighter than the stock light. Maybe even less bright. I followed the link in this article and ordered the bulb through Amazon and received a Zero 6000k “super bright” DE3021, which says it is a compatible replacement for the DE3175, 12.8v 1w bulb. Did the swap and the light is very disappointing. Any thoughts? Did I receive the wrong bulb? Are my expectations wrong?
