⚠️ Safety & Precautions

• ⚠️ Let bulbs cool first—old bulbs can be hot enough to burn you.
• ⚠️ Turn the light switch OFF and remove the key before starting.
• ⚠️ Don’t touch new bulb glass with bare fingers (if glass type); skin oil can shorten bulb life.
• ⚠️ If you must disconnect the battery: remove the negative cable first and reinstall it last.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify which “taillight bulbs” you’re replacing

• Use your work light and look at the rear lens sections.
• If the bulb is for running lights + brake/turn, it’s usually a dual-filament bulb (often labeled on the bulb base).
• Tip: The old bulb number is printed on the base.

Step 2: Remove the taillight housing (one side)

• Use a Phillips #2 screwdriver to remove the two screws holding the taillight to the body.
• Gently pull the taillight housing straight back.
• If it feels stuck, use a trim panel removal tool to gently help it release from the alignment pins.
• Torque: If no torque spec is available, reinstall screws snug by hand—do not overtighten.

Step 3: Remove the bulb socket

• Reach behind the housing and find the socket for the bulb you’re replacing.
• Twist the socket counterclockwise about 1/4 turn by hand, then pull it out.
• If it’s tight, use a nitrile gloves grip and steady pressure—don’t force the wires.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket by hand.
• Install the new bulb by pushing it straight into the socket until fully seated.
• If you’re using it, put a tiny smear of dielectric grease on the socket seal (not on the bulb contacts).

Step 5: Reinstall the socket and test

• Reinsert the socket into the housing and twist clockwise until it locks.
• Before bolting the housing back on, test the light:
  • Turn on parking lights to check the taillight/running light.
  • Press the brake pedal to check the brake light (a helper makes this easier).
  • Turn on the hazard lights to check turn signal function.

Step 6: Reinstall the taillight housing

• Align the housing with the body alignment pins and press it into place.
• Install the screws using a Phillips #2 screwdriver.
• Torque: If no torque spec is available, tighten screws snug by hand—stop when the housing is secure.

Step 7: Repeat on the other side

• Repeat Steps 2-6 for the other rear taillight.

✅ After Repair

• Verify: running lights, brake lights, turn signals, and hazards all work on both sides.
• Check that both housings sit flush and don’t wiggle.
• If a new bulb doesn’t light, re-check the socket is fully twisted/locked and the bulb is fully seated.
