This page covers the 2006 Toyota Highlander and helps you verify the correct bulb size by lighting position, so you can match the right lamp before ordering. Because trim level, body style, and market can change the fitment, it is best to use the bulb location on the vehicle as your guide instead of relying on a single universal part number.

For the 2006 Highlander, several exterior and interior lights use different bulb types depending on the function. Common fitments on this page include 9005 for the high beam headlight and daytime running light, 921 for the center high mount stop light and back up reverse light, and 7440A or 7443R for certain rear signal and brake/tail applications. Interior and small exterior lamps may use 168, 917, DE3175, or 2721 bulbs.

Before buying, compare the bulb listed for your exact position with the bulb already installed in your 2006 Toyota Highlander. Trim and lighting package differences can affect whether your vehicle uses a base halogen bulb, a different rear lamp style, or an LED replacement setup. If you are converting from halogen to LED, check polarity, bulb depth, and whether the housing has enough space for the new bulb and any built-in resistor or adapter. Aftermarket conversions can also change brightness and beam pattern, so it is smart to confirm fitment and function before purchasing a full set.
