Easiest Tesla Model 3 Headlight Replacement Method

If you’re looking to replace the headlights on your Tesla Model 3, you’re in luck. With the right tools and some patience, you can easily replace the headlights at home. Here’s a step-by-step guide to help you get started.

Tools Required

Before you begin, make sure you have the following tools:

• A pair of gloves
• OEM headlights
• Flat-head screwdriver
• Philips screwdriver
• Plastic pry bar
• Socket extensions
• 1/4″ or 3/8″ ratchet
• 10mm socket
• Flush cuts
• Plastic tray or sealable bags
• A clean cloth
• Glass cleaner
• Masking tape
• APE ethernet cable

Step 1: Take Out the Plastic Panel/Tub

To start, power off your Tesla and cover your hands with gloves. Open the hood using the app or key fob and pull the top cowl off using your bare hands. Detach the frunk latch and take out the plug. Press the 2 plastic tabs that hide the 10 mm bolts underneath (on the top of the storage cover). Grab the 10 mm socket to detach the bolts. You’ll now find another 2 bolts right in the front next to the frunk latch part. Detach the air intake cabin in the top part. Then, you’ll find a 10 mm bolt close to the master cylinder res. and unscrew it using the 10 mm socket. Take out the mat from the frunk storage to find 2 bolts at the bottom. Unscrew them using the 10 mm socket. At the top-corner section, pull up the whole front cover that hides the interior parts. If needed, use a plastic pry bar.

Step 2: Detach the Bumper

Next, you’ll need to detach the bumper. You’ll find six 10 mm bolts on top of the bumper. Detach them using the 10 mm socket. Store the bolts in a plastic tray or sealable bag. If possible, place a sticker or name the stored 6 bolts in separate tags to identify each bolt without being confused. Go down near the front-right wheel side, take a flat-head Philips screwdriver, and simply pop up the tabs on the 3 clips on the fender liner side. If needed, use the pry bar to do it easily. Pull out the fender liner using your hand. You’ll now locate three 10 mm bolts that hold the bumper to the fender area. Insert a 10 mm socket in the 1/4” or 3/8” ratchet and then remove the 3 bolts. Using the same tool, take out the one 10 mm nut on the rear corner of the bumper. Do the same procedure on the opposite (front-left) side of the Model 3. Using the Philips screwdriver and a separate flat-head screwdriver, detach the clips on the bottom front of the bumper. Just use the flathead screwdriver on the gap of clips and place a Philips screwdriver in middle to detach them. Put on masking tape on the border of the fender to avoid catching scratches upon the bumper removal. Repeat the same thing on the opposite side of Model 3. Take out the bumper away from the fender carefully and store it in a safe spot. Make sure to use slight force to do it easily. If possible, ask a friend to help you remove the bumper in a safe way. Detach the fog light harness plug using a flat-head screwdriver.

Step 3: Remove the Headlights

Now it’s time to remove the headlights. Spot 2 main bolts (10 mm) that hold the right headlight assembly. Take the 10 mm socket to remove these bolts. Be sure to use your leg to hold the headlight while removing the bolts to avoid falling out. Detach the OEM left headlight assembly. Unplug the harness plug using the flat-had screwdriver toward the tab. Do the same procedure on the opposite side to detach the OEM left headlight assembly. Store them in a good spot.

Step 4: Install the New Headlights

Once you’ve removed the old headlights, it’s time to install the new ones. Insert the front-right headlight assembly on the right side. Be sure to align the dowel into the grommet on the fender to ensure proper fitting. Insert the two 10mm bolts and tighten them out using the socket. Repeat the above steps to install the front-left headlight assembly on the left side.

Step 5: Add Ludicrous Harness

Next, adjust the ludicrous harness inside the frunk front side and use zip ties to adjust the position (if needed). Insert one side of the ludicrous harness on the bottom of the right headlight and another side on the
