⚠️ Safety & Precautions

• ⚠️ Turn headlights OFF and let bulbs cool 10+ minutes (they get very hot).
• ⚠️ Do not touch the new bulb glass with bare fingers; skin oils shorten bulb life.
• ⚠️ Keep keys out of the ignition to avoid lights turning on unexpectedly.
• Battery disconnect is not required for this repair.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify which bulb you’re replacing

• From behind the headlight housing, find the round bulb/socket you can twist out by hand.
• Most Base Crosstreks use H11 for low beams and 9005 for high beams.
• Low beam is usually the one that burns out.

Step 2: Create a little working room (if needed)

• If your hands don’t fit comfortably, remove a couple of nearby plastic push-clips using a trim clip remover and gently move the intake snorkel/cover aside (don’t force it).
• Use a flashlight to confirm you can reach the bulb socket straight-on.

Step 3: Disconnect the bulb connector

• Grip the wiring connector at the bulb (not the wires).
• Press the release tab and pull the connector off by hand. Use nitrile gloves for better grip.

Step 4: Remove the old bulb

• Twist the bulb/socket counterclockwise (left) about a quarter-turn by hand, then pull it straight out.
• Use a flashlight to make sure the bulb comes out level and doesn’t snag.

Step 5: Install the new bulb

• With nitrile gloves on, insert the new bulb into the headlight housing in the same orientation as the old one.
• Twist clockwise (right) until it locks/snugs into place (hand-tight only).
• If you accidentally touch the glass, wipe it clean with alcohol (not included) and let it dry before installing.

Step 6: Reconnect the connector

• Push the connector back onto the bulb until you feel/hear it click.
• Optional: apply a tiny amount of dielectric grease to the connector seal (not on the bulb glass).

Step 7: Repeat on the other side

• Repeat Steps 2–6 for the other headlight so both sides match in brightness.
• Reinstall any push-clips you removed using the trim clip remover.

✅ After Repair
