The dash lights on the Toyota Avalon help the driver see the instrument panel gauges and indicator lights in the dark. If any of the lights on the Avalon's instrument panel go out, it is best to replace them immediately as they are important to your safety. The Avalon uses 161-type bulbs, which can be purchased at most auto parts stores.
Open the Avalon's hood and pull off the negative terminal of the battery with a socket wrench. Wait 90 seconds for the air bags to disable.
Tilt the steering wheel to its lowest point. Insert a slotted screwdriver into the covers of the steering wheel column and pry the upper and lower cover off.
Remove the two cover screws from the instrument panel and remove the cover with a Phillips screwdriver. Pull off the lower dash trim panel below the instrument panel.
Remove the four retaining screws from the instrument panel with a Phillips screwdriver. Remove the instrument panel by pulling it out of the Avalon. Disconnect the light connector and the speedometer cable.
Turn any old bulbs counterclockwise and pull them to remove them. Install the new bulbs by inserting them into the instrument panel and turning them clockwise.
Insert the instrument panel into the Avalon and reinstall the screws and cover. Reattach the steering wheel column covers and reconnect the battery. Close the hood.
