Toyota 4Runner

Ready to upgrade those old halogen bulbs in your 2022-2023 Toyota 4Runner Headlight LED bulbs? It’s a great way to enhance your vehicle’s visibility, safety, and style. LED bulbs offer brighter illumination, greater energy efficiency, and a longer lifespan compared to traditional halogen bulbs. Let’s go to check out the installation steps!

LED Headlight Bulbs Installation Steps

Step 1: Locate the Low/ High/ Fog light, Open the hood, and locate the back of the headlight assembly. The low beam bulb is typically housed in the outermost part of the assembly; The high beam bulb is usually situated closer to the center of the headlight assembly; For the front fog light, depending on your 4Runner’s configuration, you may need to remove the front bumper or access the fog light housing from underneath the vehicle. Consult your owner’s manual for specific instructions.

Step 2: Remove the Old Bulb: Twist the bulb socket counterclockwise to remove it from the headlight housing. Carefully pull the bulb out of the socket.

Step 3: Install the New LED Bulb: Handle the new LED bulb with gloves to avoid touching the glass. Insert the new bulb into the socket and twist it clockwise to secure it in place.

Step 4: Reconnect the Headlight Assembly Socket: Once the new bulb is installed, reconnect the positive, and negative terminal of the plug and test the lights to ensure proper installation.

Congratulations! You have successfully installed LED headlight bulbs in your vehicle. Not only do LED headlight bulbs provide improved visibility and safety on the road, but they also contribute to energy conservation.

Final Check Adjust the LED Light Bulb Angle

1: Check Alignment: Ensure that the new LED bulbs are properly aligned. Misaligned headlights can cause glare and reduce visibility.

2: Test All Lights: Turn on the headlights and fog lights to verify that all bulbs are working correctly. Check for consistent illumination and proper beam patterns.

3: Secure Components: Ensure all components and covers are securely in place. Close the hood and make sure the battery terminals are tightly connected.
