Bulb size chart
This 2009 Acura TL bulb size guide is built to help you verify the correct bulbs by lighting position, so you can match the right replacement to the right socket. Whether you are replacing an exterior lamp or an interior convenience light, this page organizes the common fitment points for the 2009 Acura TL in a simple way.
Use this page to check the bulb type for each location on the vehicle, including headlights, turn signals, brake lights, license plate lights, dome and map lights, and other interior and cargo-area lamps. The 2009 Acura TL can use different lighting setups depending on trim, market, and body style, so confirming the bulb by position is the safest way to shop.
Fitment can vary on the 2009 Acura TL, especially when comparing trim levels, lighting packages, and regional specifications. Some positions use factory LED assemblies, while others use halogen or HID-style bulbs, so it is important to match the original design before ordering. If you are considering an aftermarket LED conversion, check whether the bulb is compatible with the housing, connector, and beam pattern, since a bulb that physically fits may still perform poorly or trigger issues. For the best results, inspect the installed bulb before purchase and compare it with the listing on this page, especially for items like the low beam, fog light, and interior bulbs where options can differ.
