For many Toyota Tacoma owners, the OEM halogen headlight bulbs don’t provide adequate performance at night. Upgrading to LED headlight bulbs can significantly enhance brightness, driving safety, and overall visibility. In this guide, we’ll walk you through the process of replacing the low beam bulbs on a 2018 Toyota Tacoma TRD Off-Road 4x4 with the best replacement headlight bulb—LSplusH11.
Step 1: Locate the Bulbs
• Open the hood of your Tacoma and look at the back of the headlight assembly.
• You will see three bulbs: the turn signal, the high beam, and the low beam. The low beam bulb is all the way toward the fender, tucked in the corner.
Step 2: Remove the Factory Bulb
• Disconnect the Wiring Harness: Press down on the small clip and slide the connector off.
• Remove the Bulb: Twist the bulb counterclockwise and pull it out.
The factory low beam uses an H11 bulb. The high beam is labeled H9, but don’t worry—4th Gen Lasfit LSplusH11 LED bulbs will also fit H9, H8, and H16 sockets, so upgrading to Toyota Tacoma LED headlights won’t be a problem.
Step 3: Install the New LED Bulb
• Prepare the Bulb: The Lasfit LS Plus Series comes with a 360° adjustable base. Rotate the base all the way counterclockwise until it locks. Doing this first will save you time during installation.
• Insert the Bulb: Place the LED bulb into the socket and twist it to lock. Make sure the LED chips face left and right (3 o’clock to 9 o’clock). This step ensures that you are installing one of the brightest LED bulbs available, ideal for improved road visibility.
• Check Wiring Direction: The connector should usually face downward when properly seated.
• Connect the Harness: Plug in the connector to the bulb——The Lasfit LS Plus bulbs are plug-and-play, meaning they require no additional modifications. This makes the tacoma LED headlight bulb installation process easy and seamless.
Step 4: Tests the Lights
• Test the Bulb: Before fully assembling the headlight assembly, test the new Toyota Tacoma LED headlight bulbs by turning on the headlights. If the bulb does not light up, flip the plug and reconnect it—Lasfit LS Plus bulbs are polarity-sensitive.
• Adjust the Beam Pattern: The Lasfit LS Plus features a 360° adjustable collar, if the beam pattern isn't aligned properly, you can rotate the collar to adjust it. This feature ensures that you get the most stable LED headlight bulbs with a perfect beam pattern for your Toyota Tacoma.
Conclusion
Replacing the headlight low beam bulbs on a 2018 Toyota Tacoma is very simple:
1.Disconnect the harness → 2. Twist out the old bulb → 3. Insert the new bulb → 4. Adjust the direction → 5. Reconnect the harness.
The process doesn’t require extra tools, so even beginners can complete it easily. If you're looking for brighter and clearer visibility, we highly recommend the 4th Gen Lasfit LSplusH11 LED bulbs. With 65W and 6500LM, these LED bulbs shine up to 700% brighter than standard halogen, providing optimal lighting for your Tacoma LED headlights. These bulbs fit H9/H8/H16 sockets, so you can upgrade both low and high beams with the same tacoma LED headlight bulb.
