This tutorial provides a comprehensive guide on installing LED headlights in a 2019 Subaru WRX. Upgrading to LED headlights can significantly improve visibility and modernize your vehicle. This step-by-step guide outlines the tools needed, detailed instructions, and practical tips to ensure a successful installation.

Step 1: Gather Your Materials

Before starting the installation, collect the following items:

• SEALIGHT Scoparc S1 H11/H8/H9 LED Headlight Bulbs
• Socket set (including a 10mm socket)
• Zip ties (included with LED kit)
• Extension for socket wrench (for hard-to-reach bolts)
• Optional: Double-sided sticky tape

Step 2: Prepare the Vehicle

1. Safety First

   • Park your Subaru WRX on a flat surface and turn off the ignition.
   • Disconnect the battery to prevent any electrical issues.

2. Access the Headlight Area

   • For the passenger side, you will need to remove part of the airbox for access:
     • Remove the front vent by popping off clips.
     • Unscrew the 10mm bolt securing the airbox.

Step 3: Remove the Old Headlight Bulb

1. Access the Bulb

   • With the airbox partially removed, locate the low beam bulb (the one you will replace).
   • Disconnect the wiring harness from the old bulb.

2. Remove the Bulb

   • Twist the bulb socket counterclockwise to release it from the housing.
   • Pull the old bulb out gently.

Step 4: Install the New LED Bulb

1. Insert the New Bulb

   • Take the new LED bulb and insert it into the housing.
   • Twist the bulb socket clockwise to secure it in place.

2. Connect the Wiring

   • Connect the wiring harness to the new LED bulb.
   • Ensure the connection is secure.

Step 5: Reassemble the Airbox

1. Position the Airbox

   • Set the airbox back into position without tightening it completely.
   • Ensure it aligns with the clips at the bottom.

2. Secure the Airbox

   • Tighten the bolt you previously removed.
   • Ensure all clips are securely fastened to avoid air leaks.

3. Tidy Up Wires

   • Use zip ties to tuck away any loose wires from the LED installation to prevent interference with the airbox.

Step 6: Repeat for the Driver's Side

1. Access the Driver's Side

   • The driver’s side headlight can be accessed more easily by reaching behind the battery.
   • Disconnect the battery if not already done.

2. Follow Steps 3 to 5

   • Repeat the process of removing the old bulb, installing the new LED bulb, and reassembling the airbox.

Conclusion

After completing the installation on both sides, reconnect the battery and test the new LED headlights to ensure they function correctly. Upgrading to LED lights can enhance your visibility on the road and improve the overall look of your Subaru WRX. Keep an eye on the headlights for any issues, as prolonged use may reveal potential pitfalls, such as water ingress. If you experience issues, consider upgrading to full new headlights. Enjoy your improved lighting and safe driving!
