🔧 Highlander - Headlight Bulb Replacement

On your Highlander XLE, the “headlights” are typically LED low/high beams, which usually do not have a replaceable bulb—you replace the entire headlamp assembly if an LED fails. Some other front bulbs (like turn signal/parking) are replaceable.

Difficulty Level: Intermediate | Estimated Time: 0.5-2.5 hours (depends on which light)

⚠️ Safety & Precautions

• ⚠️ Turn the lights OFF and let the housing cool before touching anything.
• ⚠️ If you’re working near wiring connectors, disconnect the negative battery terminal with a 10mm wrench.
• ⚠️ If your lamp uses a halogen bulb, don’t touch the glass—skin oil can shorten bulb life.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which “headlight” is out

• Turn the lights on and identify the failed function: low beam, high beam, turn signal, or parking/marker.
• Use a flashlight to look at the headlamp—LED low beams are usually a bright white projector-style light.

Step 2: Access the rear of the headlamp (basic access)

• Open the hood and locate the rear covers/connectors behind each headlamp.
• If a cover or liner blocks access, remove fasteners using a trim clip removal tool and 10mm socket.
• Tip: Keep clips in a cup.

Step 3: If it’s an LED low/high beam failure (common on XLE)

• There is typically no replaceable “bulb” for the LED low/high beam—replacement is the headlamp assembly.
• To replace the assembly, you usually must loosen/remove bumper cover fasteners and then remove headlamp mounting bolts using a 10mm socket, ratchet, and extension.
• Disconnect the headlamp electrical connector(s) by hand (press tab and pull straight).
• Tip: Don’t pry on the lens.

Step 4: If it’s a replaceable bulb (turn signal / marker)

• Twist the bulb socket counterclockwise by hand to remove it from the housing.
• Pull the bulb straight out (or twist, depending on socket style).
• Install the new bulb fully, then reinstall the socket and twist clockwise to lock.
• If you removed liners/clips, reinstall them using the trim clip removal tool and 10mm socket.

Step 5: Reconnect battery and verify operation

• Reconnect the negative battery terminal using a 10mm wrench.
• Test low beams, high beams, turn signals, and hazards.

✅ After Repair

• Verify both sides match brightness and color.
• If a headlamp assembly was replaced, check the beam aim on a flat wall at night; aim issues can reduce visibility.
• Make sure all clips/liners are secured so nothing rubs the tire.
