Second Small Notch
This automotive maintenance tutorial was specifically written to assist owners of the fifth generation (2019, 2020, 2021, 2022 and the revised 2023 model year) Toyota RAV4 SUV in changing a burnt out dome light bulb located in the housing attached to the headliner above the rear passenger seats.

Owners of other Toyota and Lexus vehicles such as the Camry, Corolla, Highlander, Prius, Avalon, C-HR, GR86, Venza, Sienna, Sequoia, 4Runner, IS 250, IS 300, IS 350, ES 350, GS 350 and GX 460 may also find these DIY instructions to be helpful.

The OEM light bulbs in this 2019 RAV4 were marked as part number Toshiba 12V8WAL:8Z.

The compatible replacement aftermarket "festoon" style light bulb part number is DE3175.

If you'd like to have a brighter dome light that will last much longer before burning out like the traditional incandescent bulb, install a DE3175 LED unit.

The only tool needed to remove the lens cover and access the bulb socket is a small flat head screwdriver such as from a precision screwdriver set or a small plastic pry bar tool.

I found it easiest to change the dome light bulb by sitting in the second row of passenger seats.

Locate the two small notches on the front edge of the lens cover (closest to the front of the vehicle).

To prevent from scratching the plastic surfaces, I recommend either covering the tip of your screwdriver with some painter's tape or a thin micro fiber cloth, or instead use a small plastic pry bar tool.

Insert the blade of the screwdriver into one of the two notches on the front edge (close to the "Off / Door / On" switch) and gently pry out the lens cover.

You may need to remove and reinsert the screwdriver into the other notch to fully remove the lens cover.

Try to avoid using excessive force. The lens cover should pop out relatively easily.

Do NOT pry along the rear edge of the lens cover since there are two larger plastic tabs on that side could be broken.

Old Bulb Exposed
Set the lens cover aside in a safe place.

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

Allow the old light bulb to cool off before handling it.

Empty Bulb Socket
Gently pull back the flexible metal electrical contact on the left (driver) side of the bulb socket to release the old bulb.

Remove the old bulb from the socket.

In this 2019 RAV4, the OEM (original equipment manufacturer) light bulb was marked as part number Toshiba 12V8WAL:8Z (or perhaps it was 12V8WAL:82).

Reinsert Tabs Rear Edge
Gently install the new DE3175 light bulb into the socket.

To test the new light bulb, slide the "Off / Door / On" switch to the "On" setting.

Tip - If you installed an LED bulb and it doesn't work, try removing it from the socket, rotate it 180 degrees and push it back into the socket. Some LED bulbs are "polarized" and will only work when the "+" positive and "-" negative electrical contacts are in the correct orientation.

Line up the lens cover with the opening in the light housing.

Slide Switch To "Door"
First, reinsert the two tabs on the rear edge.

Then gently snap in the retaining clips on the front edge back into place.

I recommend moving the switch to the "Door" setting so that the dome light will turn on any time the driver door or a passenger door is opened.

Be sure to record the bulb change in your vehicle's service records.
