DIY Bulbs, LED Info, and What to Leave to the Dealer

The 2025 4Runner includes a mix of standard replaceable bulbs and sealed LED units. Toyota allows some exterior bulb replacements to be done by owners but recommends dealer service for most interior and LED-equipped fixtures.

Owner-Replaceable Bulbs​

The following can be replaced by the owner with basic tools:
  • Side marker lights
  • Side turn signal lights
  • Tail lights
  • Stop lights
  • Back-up lights
  • Rear turn signal lights
  • License plate lights
  • High-mounted stoplight
  • Trailer hitch light
Always verify the wattage on page 623 and match the part number before replacing.

Front Turn Signal / Parking Lights (Bulb Type)​

Only applicable if your 4Runner came with non-LED housings:
  1. Remove the 5 push clips and the air cleaner inlet (passenger side only)
  2. Turn the bulb base counterclockwise
  3. Pull out and replace the bulb
  4. Reinstall in reverse order

Important Warnings​

  • Always turn off the lights and let them cool before handling
  • Do not touch the glass part of the bulb—use a clean, dry cloth
  • Make sure bulbs are fully seated and locked to prevent moisture or fire risk
  • LED lights are non-serviceable; take your vehicle to a Toyota dealer if they fail
  • Never use a bulb with a different wattage or substitute with non-Toyota parts

Signs of Bulb Failure​

  • Flickering or dim lights
  • Warning light on the dash
  • Lens condensation or moisture inside the housing
  • No illumination when switched on
