Illuminate Your Ride: A Step-by-Step Guide to Upgrading Your Toyota 4Runner Interior Lights to LED

The Toyota 4Runner, especially the 5th generation, is renowned for its ruggedness and off-road prowess. However, one area where many owners find room for improvement is the interior lighting. The factory amber-colored lights, while functional, often feel dim and outdated, failing to provide adequate illumination. If you’re looking to brighten up your 4Runner’s cabin and give it a more modern feel, upgrading to LED interior lights is a fantastic DIY project.

This guide will walk you through the process of replacing your 5th generation Toyota 4Runner’s interior lights with brighter and more efficient LED lights. We’ll cover each type of interior light, from the lower door lights to the map lights, providing step-by-step instructions to make this upgrade straightforward and satisfying.

First, let’s take a look at the components you’ll be upgrading.

Tools You’ll Need

Before you begin, gather these simple tools to ensure a smooth and damage-free installation:

• Interior Pry Tool or Small Screwdriver: For gently prying out light assemblies. A plastic pry tool is recommended to minimize the risk of scratching interior trim, but a small flathead screwdriver can also work with caution.
• Replacement LED Bulbs: Purchase a set of LED interior lights specifically designed for the 5th Gen Toyota 4Runner. Kits are readily available online from reputable vendors, often including bulbs for the map lights, dome light, and door lights. Ensure you have the correct number and type of bulbs for your vehicle.
• Optional: Needle Nose Pliers (with electrical tape): May be helpful for removing map lights, but not strictly necessary if you follow the console removal method described later.

Once you have your tools and LED kit ready, let’s dive into the installation process.

Step-by-Step Guide to LED Interior Light Upgrade

This guide is broken down by light type for ease of use. Remember to work in a well-lit area and take your time to avoid damaging any components.

Upgrading the Lower Door Lights

The lower door lights on the 4Runner are notoriously dim from the factory. Upgrading these to LEDs will significantly improve visibility when entering and exiting your vehicle at night.

1. Pry Out the Light Assembly: Using your pry tool or screwdriver, gently insert it into the side of the light housing, as shown. Focus on the right side of the light in the middle portion.

2. Remove the Assembly: Once you pry gently, the assembly will pop loose from the door panel.

3. Disconnect the Power Clip: Detach the electrical connector from the back of the light assembly.

4. Separate the Housing: Locate the small tab on the side of the light assembly. Pry this tab up and slide the grey part of the housing to separate it from the clear cover.

5. Access the Bulb: Gently remove the grey hood to expose the factory bulb.

6. Replace with LED: Pull out the old bulb and insert the new LED bulb.

7. Test the LED: Before reassembling, reconnect the power clip to the light assembly and test if the LED illuminates. LEDs are polarity sensitive, so if it doesn’t light up, remove the LED, rotate it 180 degrees, and reinsert. Test again. This step is crucial to avoid re-disassembly later.

8. Reassemble the Housing: Once tested, reattach the grey hood and then snap the clear cover back onto the assembly.

9. Reinstall in Door: Reconnect the power cable and insert the left side of the assembly into the door panel first, then push the right side until it clicks securely into place.

Repeat these steps for the remaining three lower door lights.

Replacing the Rear Door Dome Lights

The rear door dome lights are also straightforward to upgrade. The process is similar for both driver and passenger sides.

1. Pry Out the Light Assembly: Locate the driver’s side edge of the light assembly. Use your pry tool or screwdriver to gently push upwards. This action will depress a metal clip that secures the light.

2. Slide Out the Assembly: Once the clip is released, the light assembly will slide out and hang by its power cable.

3. Remove the Cover: The clear cover is held in place by four tabs around the edge. Carefully pry these tabs to remove the cover. Be gentle as these tabs can be fragile.

4. Access and Replace the Bulb: The bulb is held in place by two points. One of these is a flexible tab. Push down on the flexible tab (located at the bottom of the light in this case) to release the bulb. Remove the old bulb and insert the LED replacement, ensuring the LEDs are facing outwards for optimal light distribution.

5. Test the LED: Flip the light switch to the “ON” position to test the LED. Reverse polarity if it doesn’t light up.

6. Reassemble and Reinstall: Reattach the clear cover, then reconnect the power cable. Slide the power cable side of the assembly back into the opening first, and then press the side with the metal clip until it pops back into place.

Repeat for the other rear door dome light.

Swapping the Interior Dome Light

Upgrading the main interior dome light will make a significant difference in overall cabin brightness.

1. Remove the Cover: Unlike the door lights, the dome light assembly stays mounted to the ceiling. Locate the two slots on the side of the cover facing the front of the 4Runner (the side with the switch). Use your pry tool to gently pop the cover off at these points.

2. Access and Replace the Bulb: Similar to the rear dome lights, there is a flexible metal tab holding the bulb in place. It can be a tight space, especially for larger hands. Carefully remove the old bulb and insert the LED replacement.

3. Test the LED: Test the LED by turning the dome light switch on. Reverse polarity if necessary.

4. Reattach the Cover: Once confirmed working, simply snap the cover back onto the dome light assembly.

Installing LED Map Lights

The map lights are often the trickiest to access. While some may be able to remove the bulbs directly, removing the upper console provides much easier access and minimizes frustration.

1. Pry Down the Crawl Control Box (if equipped): On the windshield side of the crawl control box (if your 4Runner is equipped), you’ll find two openings. Insert your pry tool into these openings and gently pry downwards. The crawl control box will detach.

2. Disconnect and Remove Crawl Control Box: Disconnect the electrical connector from the crawl control box and set the box aside.

3. Remove Console Bolts: In the cavity where the crawl control box was, you’ll see two bolts (likely 8mm). Remove these bolts.

4. Pull Down the Upper Console: Gently pull down on the upper console. It is held in place by two connectors that will pop loose. Be careful not to pull too forcefully as there are still wires attached.

5. Access the Map Light Bulbs: On the backside of the console, you’ll find two black connectors. Turn these connectors about a half turn to remove them along with the factory bulbs.

6. Install LED Bulbs and Test: Insert the LED bulbs into the connectors. Before reassembling, test the LEDs to ensure they work.

7. Reinstall Upper Console: Reinstall the upper console by reversing the removal process. Reconnect any wires, pop the console back into place, and reinstall the bolts and crawl control box.
