This page covers the 2009 Toyota 4Runner bulb sizes by lighting position, so you can quickly match the correct replacement before ordering. Whether you are changing a map light, dome light, cargo light, or glove box bulb, this guide is meant to help you verify fitment for the specific location on the vehicle.
The 2009 Toyota 4Runner uses several different interior bulb types, and the correct size depends on where the bulb is installed. Use the bulb chart on this page to compare each lighting position with the listed bulb sizes and avoid guessing when replacing a burned-out interior lamp.
Fitment can vary by trim, lighting package, market, and body style, so it is smart to confirm the bulb already installed before you buy replacements. Some owners choose LED upgrades instead of halogen-style bulbs, but aftermarket conversions can change brightness, color, and heat output, and not every LED replacement fits the housing the same way as the original bulb. If you are switching from halogen to LED, check polarity, physical clearance, and whether the lens or reflector is designed for the new bulb style. When possible, compare the old bulb directly to the new one before installation, especially for positions like the dome, cargo, and courtesy lights where small differences can affect the final fit.
The listed interior bulb sizes for the 2009 Toyota 4Runner include 168 or 917 for the map light, 194 or 7441 for the interior door light and courtesy light, DE3175 for the trunk or cargo area light and dome light, and 37 for the glove box light.

Yes, many owners upgrade to LED bulbs, but you should confirm fitment, polarity, and clearance before installing them in the 2009 Toyota 4Runner.
Not always. Some LED replacements fit physically but may sit differently in the housing, change the light pattern, or require polarity correction.
They are the listed sizes for this year and model, but exact fitment can still vary by market, trim, and lighting equipment, so verification is recommended.
First check that the bulb is seated correctly and matches the required size. If you are using an LED bulb, try reversing it if polarity is an issue.
