Owners of other Toyota, Lexus or Scion vehicles such as the Corolla, Matrix, Prius, Camry, RAV4, Sienna, Tacoma, Tundra, FJ Cruiser, Venza, Highlander, Avalon, Sequoia, Land Cruiser, IS 250, ES 350, GS 350, tC, xB, xD, iQ and FR-S may also find these DIY instructions to be helpful.

The compatible replacement festoon or "fuse" style light bulb is part number DE3022.

You can also use a brighter DE3022 LED bulb.

The only tool needed to access and replace the cargo area or trunk light bulb is a small flathead screwdriver or a plastic automotive panel pry bar tool.

Locate the notch on the rear edge of the tail light bulbs access panel.

Use a small flathead screwdriver or a plastic automotive panel pry bar tool to gently remove the access cover.

Set the access cover aside in a safe place.

Carefully reach in and pop out the cargo area light bulb housing from the plastic panel.

Try to avoid touching the rear of the light housing for too long since it might be hot enough to burn your fingers. For extra safety, I recommend wearing a glove.

Press in the release tab on the white plastic electrical connector before sliding the power plug straight out of the socket.

Be careful when you remove the old light bulb. If it was recently turned on, it might still be hot enough to burn your fingers.

Gently pull back one of the metal electrical contacts and remove the old bulb from the socket.

Tip - If you are installing an LED bulb and it doesn't work at first, try flipping it around in the socket.

Push the power plug back in to the socket on the light housing.

Re-insert the light housing in to the cargo area panel and snap it back in to place.

The new cargo area light bulb should have turned on as soon as you re-inserted the power plug.

If it didn't turn on, test the new light bulb by activating the interior lights by pressing the "Unlock" button on the key fob or by turning on the headlights.
