🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood

• Use your hand to release the hood latches on both sides of the hood.
• Lift the hood and secure it with the hood prop rod.
• Put on safety glasses before working around the grille clips.

Step 2: Remove the upper grille clips

• Use the flat trim removal tool to lift the center pin of each plastic push clip along the top of the grille.
• Once each center pin is raised, pull the whole clip out by hand.
• Set the clips on a microfiber towel so they do not roll away.
• Work slowly to avoid breaking clips.

Step 3: Release and remove the front grille

• Use both hands to gently pull the top of the grille forward.
• Use steady pressure to release the lower grille retaining clips from the body.
• Lift the grille away from your Wrangler and place it face-up on a microfiber towel.
• Do not yank the grille. The lower clips release with a firm straight pull.

Step 4: Remove the headlight retaining ring

• Choose one headlight to start with.
• Use a Phillips #2 screwdriver to remove the screws holding the metal headlight retaining ring.
• Hold the headlight with one hand as you remove the last screw so it does not fall forward.
• No torque spec is published for these small retaining-ring screws. Reinstall them snug only.

Step 5: Pull the headlight assembly forward

• Use both hands to carefully pull the headlight assembly forward just enough to reach the electrical connector.
• Do not pull hard on the wiring harness.

Step 6: Disconnect the old bulb

• Use your fingers to press the locking tab on the headlight connector.
• Pull the connector straight back off the bulb.
• If it feels stuck, gently wiggle the connector while pulling straight back.
• Do not pry the connector with a screwdriver because the plastic lock can break.

Step 7: Remove the old bulb

• Use your gloved hand to rotate the old H13 halogen headlight bulb counterclockwise.
• Pull the bulb straight out of the headlight housing.
• Inspect the bulb opening for dirt or moisture before installing the new bulb.

Step 8: Install the new bulb

• Use clean nitrile gloves to handle the new H13 halogen headlight bulb.
• Line up the tabs on the bulb with the slots in the headlight housing.
• Insert the bulb straight into the housing.
• Rotate the bulb clockwise until it locks in place.
• Never touch the bulb glass.

Step 9: Reconnect the wiring

• Apply a tiny amount of dielectric grease to the rubber seal area of the connector, not packed into the metal terminals.
• Push the electrical connector onto the bulb until the lock clicks.
• Gently tug the connector by hand to confirm it is fully seated.

Step 10: Reinstall the headlight assembly

• Position the headlight assembly back into the bucket.
• Install the metal retaining ring by hand first.
• Use the Phillips #2 screwdriver to tighten the retaining-ring screws evenly.
• Tighten the screws snug only. Do not overtighten because the small screws and headlight tabs can strip.

Step 11: Repeat on the other side

• Use the Phillips #2 screwdriver to remove the retaining-ring screws on the opposite headlight.
• Repeat the same bulb removal, installation, connector, and retaining-ring steps.
• Replace both bulbs before reinstalling the grille.

Step 12: Test the headlights before reinstalling the grille

• Turn the key to the accessory position if needed.
• Use the headlight switch to turn on the low beams.
• Use the multifunction stalk to check high beams.
• Confirm both headlights work on low beam and high beam.
• Turn the headlights off after testing.

Step 13: Reinstall the front grille

• Line up the lower grille clips with their body openings.
• Use both hands to press the grille straight into place until the lower clips seat.
• Install the upper plastic push clips by hand.
• Press the center pins down flush using your thumb or the flat trim removal tool.

Step 14: Close the hood

• Remove the hood prop rod and lower the hood carefully.
• Secure both outer hood latches by hand.
• Check that the grille is fully seated and even across the front.

✅ After Repair

• ✅ Turn on the low beams and high beams again to confirm both sides still work.
• ✅ At night, park about 25 feet from a wall and check that both beams appear level and even.
• ✅ If one beam looks much higher or lower, the headlight assembly may not be seated correctly.
• ✅ Dispose of old halogen bulbs safely. Do not leave broken glass where tires or hands can contact it.
