This procedure covers removal and replacement of the LED headlight module assembly on a 2018-2024 Toyota Camry with 2.5L I4 engine, including electrical disconnection and beam alignment verification.
Warnings
⚠LED headlight modules contain sensitive electronics. Avoid dropping or impacting the assembly during removal or installation.
⚠Do not touch the LED light-emitting surfaces with bare hands. Oil contamination can reduce light output and lifespan.
ℹ️Vehicle must be on level surface for proper headlight aiming after installation.
⚠Disconnecting battery will require radio code re-entry and may reset various vehicle settings.

Parts
- LED Headlight Module Assembly × 1 — 81110-06xxx (Driver) or 81170-06xxx (Passenger) - Use OEM specification
- Headlight module mounting grommets × 3 — Use OEM specification if damaged
Preparation
- Park vehicle on level surface and engage parking brake
- Turn off all lights and remove key from ignition
- Allow engine to cool completely if recently driven (at least 30 minutes)
- Open hood and secure with prop rod
- Disconnect negative battery terminal and wait 3 minutes for capacitor discharge
Procedure
- 1Remove upper radiator cover panelLocate and remove the plastic clips securing the upper radiator cover panel. Use trim removal tools to carefully pry up each clip. Remove the panel to access the headlight assembly mounting area. Set panel and clips aside in a safe location.
- 2Disconnect washer fluid hoseLocate the windshield washer fluid hose connected near the headlight assembly. Gently squeeze the retaining clip and pull the hose off the washer nozzle. Place a cloth underneath to catch any residual fluid drips.
- 3Remove headlight module coverLocate the rear dust cover on the back of the headlight assembly. Rotate the cover counterclockwise approximately 1/4 turn and pull it straight back to remove. This exposes the electrical connector and mounting hardware.
- 4Disconnect electrical connectorPress the locking tab on the LED module electrical connector and carefully pull the connector straight out. Do not twist or pull on the wires themselves. Inspect connector for corrosion or damage. If connector screws are present, loosen them first.Torque specConnector Screws4 Nm (3 lb-ft)
- 5Remove module mounting boltsLocate the three 10mm mounting bolts securing the headlight module to the vehicle body. These are typically positioned at the top and sides of the assembly. Use a socket with extension to access the lower bolt. Remove all three bolts completely and retain them.ℹ️Support the headlight assembly with one hand while removing the final mounting bolt to prevent it from falling.Torque specModule Mounting Bolts8 Nm (6 lb-ft)
- 6Remove headlight module assemblyWith all mounting bolts removed, carefully pull the headlight module forward and out of the vehicle. There may be alignment pins and grommets that require gentle wiggling to release. Support the assembly with both hands and avoid letting it drop or contact other components. Inspect mounting grommets for wear or damage.
- 7Transfer components if necessaryIf the new module does not include mounting grommets, brackets, or adjustment hardware, carefully transfer these from the old module to the new one. Inspect all rubber grommets for cracking or deterioration and replace if necessary. Ensure any ground straps are clean and ready for reinstallation.
- 8Clean mounting surfaces and electrical contactsUse a clean cloth to wipe the mounting surface on the vehicle body where the headlight module seats. Remove any dirt, debris, or old grease. If electrical contacts show corrosion, apply electrical contact cleaner to the vehicle-side connector and allow to dry completely before proceeding.
- 9Install new LED headlight modulePosition the new headlight module at the mounting location, aligning the mounting pins with the body openings. Ensure any ground straps are positioned correctly for connection. Gently press the module into place until it seats fully against the body. Verify alignment pins are properly engaged in their grommets.⚠Do not force the module into position. Misalignment can damage mounting pins or grommets. Ensure all alignment features are properly engaged.
- 10Install module mounting boltsThread all three mounting bolts by hand first to ensure proper alignment. Once all bolts are started, tighten them in a star pattern (alternating positions) to the specified torque. This ensures even pressure and proper seating of the module.Torque specModule Mounting Bolts8 Nm (6 lb-ft)
- 11Reconnect electrical connectorAlign the electrical connector with the LED module socket and press firmly until it clicks into place. The locking tab should engage audibly. Gently tug on the connector to verify it is secure. If connector screws are present, tighten them to specification.Torque specConnector Screws4 Nm (3 lb-ft)
- 12Reinstall rear dust coverPosition the rear dust cover over the back of the headlight assembly, aligning the tabs. Press it into place and rotate clockwise approximately 1/4 turn until it locks securely. Verify the seal is seated properly around the entire perimeter.
- 13Reconnect washer fluid hosePush the windshield washer fluid hose firmly onto the nozzle until the retaining clip engages with an audible click. Tug gently to verify secure connection.
- 14Reinstall upper radiator cover panelPosition the upper radiator cover panel in its original location and press down firmly on each clip location until all clips snap into place. Verify the panel is secure and flush with surrounding components.
- 15Reconnect battery and testReconnect the negative battery terminal and tighten the terminal bolt to specification. Do not overtighten. Turn the ignition to ON position (engine off) and test low beam, high beam, and turn signal functions. Verify LED module operates correctly without flickering or error messages on the instrument cluster.⚠Battery terminal bolts require low torque specification. Overtightening can damage the terminal or battery post.Torque specBattery Terminal Bolts6 Nm (4 lb-ft)
Reassembly
- Ensure all electrical connectors are fully seated and locked
- Verify all mounting bolts are torqued to specification
- Confirm rear dust cover is properly sealed to prevent moisture ingress
- Check that radiator cover panel clips are all engaged
- Verify washer fluid hose is securely connected
Verification
- With engine running, test low beam, high beam, DRL (if equipped), and turn signal functions on the replaced headlight
- Check for any warning lights on the instrument cluster indicating headlight system faults
- Verify beam pattern on a wall or garage door - both headlights should have symmetrical patterns at the same height
- Test washer fluid spray to ensure hose reconnection is secure
- If beam aim is incorrect, use headlight aiming adjustment screws (typically accessible from engine bay) to adjust vertical and horizontal aim per Toyota specifications
- Take vehicle for a short test drive after dark to verify proper illumination and no vibration or rattling from the new module
