The dashboard light bulb in your Toyota Sienna illuminates the instrument panel assembly. These small light bulbs should give you years of trouble-free service; however, they do eventually burn out. You can purchase these bulbs from many auto parts stores, but you will need the model year of your Sienna to make sure that you are buying the correct size of bulb for your generation of Sienna. If you’ve never done this job before, expect to spend 30 minutes changing the lights.
