This automotive maintenance tutorial was specifically written to assist owners of the third generation (2011, 2012, 2013, 2014 and also the updated 2015 & 2016 model years) Toyota Sienna minivan in changing a burnt out low beam, high beam, and front turn signal light bulb in the headlight assemblies.

Owners of other Toyota vehicles with similar headlight housings such as the Tacoma, Tundra, FJ Cruiser, Hilux, Venza, Highlander, 4Runner, Sequoia, RAV4 and Land Cruiser, may also find these DIY instructions to be helpful.

Replacement bulbs with their part numbers are as follows: Low Beam # H11, High Beam # 9005 and Front Turn Signal # 3457A (also 3457NAK or 3457NA).

No tools are needed to replace any of the headlight bulbs.

You may need rubbing alcohol and a paper towel to clean the glass part of the new halogen bulbs if they get dirty.
