Warnings

Tools required

Parts

• H11 halogen bulb or LED equivalent × 2 — H11 bulb type, OEM Honda part 33115-TVA-A01 or aftermarket equivalent

Preparation

1. Park vehicle on level surface and turn off engine
2. Allow headlights to cool if recently used (minimum 15 minutes)
3. Open hood and secure with prop rod
4. Put on clean lint-free or nitrile gloves to prevent skin oil contact with new bulbs

Procedure

1. 1

   Locate driver side headlight assembly
   From the engine bay, locate the back of the driver side headlight assembly. The low beam bulb is typically the outer bulb socket (closest to fender). You will see a large rubber dust cover with a tab or the bulb connector protruding from the back of the headlight housing.
2. 2

   Remove driver side dust cover
   Grip the rubber dust cover at the back of the headlight housing and rotate it counterclockwise approximately 1/4 turn, then pull it straight back to remove. If equipped with a tab, you may need to squeeze or lift the tab while rotating. Set the dust cover aside in a clean location.
3. 3

   Disconnect driver side bulb connector
   Locate the electrical connector attached to the back of the bulb. Press the release tab on the connector and pull straight back to disconnect. Do not pull on the wires themselves. Note the orientation of the connector for reinstallation.
4. 4

   Remove driver side bulb
   The bulb is held in place by a wire spring clip or rotating collar. If wire clip: press the clip inward and unhook it from the retaining tabs, then pivot it away. If rotating collar: turn the bulb counterclockwise approximately 1/4 turn. Pull the old bulb straight out of the socket. Avoid touching the reflector inside the housing.
5. 5

   Install new driver side bulb
   Remove the new H11 bulb from packaging, handling only the plastic base. Verify the bulb orientation tabs align with the socket slots. Insert the new bulb straight into the socket until it seats fully. Secure with the wire spring clip (hook it back over the retaining tabs) or by rotating the collar clockwise 1/4 turn until it locks.
6. 6

   Reconnect driver side electrical connector
   Push the electrical connector onto the back of the new bulb until you hear or feel a click. Gently tug to verify it is locked in place. Ensure the connector is fully seated.
7. 7

   Reinstall driver side dust cover
   Position the rubber dust cover over the back of the bulb assembly, aligning any tabs or orientation marks. Push it into place and rotate clockwise approximately 1/4 turn until it seats and seals properly against the housing.
8. 8

   Repeat for passenger side headlight
   Move to the passenger side of the engine bay and repeat steps 1-7 for the passenger side low beam bulb. Access and procedure are identical. The passenger side may have slightly more room or slightly less depending on installed accessories.

Reassembly

1. Verify both dust covers are properly seated and sealed to prevent moisture intrusion
2. Ensure no tools or parts were left in the engine bay
3. Close hood securely

Verification

• Turn ignition to ON position and activate headlights to low beam setting
• Verify both headlights illuminate with equal brightness and proper beam pattern
• Check for any flickering or warning lights on the dashboard
• Walk around vehicle to visually confirm both low beams are functioning
• If beam pattern appears misaligned, have headlight aim checked and adjusted if necessary
