Acura TSX 2009 Bulb Size
Bulb size chart
This page covers the 2009 Acura TSX and helps you verify bulb sizes by lighting position, so you can match the correct replacement before you buy. Because Acura used different lighting setups depending on trim, package, market, and body style, it is always smart to confirm the bulb listed for each lamp on your vehicle.
For the 2009 TSX, the chart includes common exterior and interior bulbs such as the low beam D2S, high beam 9005, daytime running light 9005, and several smaller interior and signal bulbs. Use the position-specific listings here to narrow down the right fit for headlights, tail lamps, plate lights, dome lights, and other locations on the car.
Fitment on the 2009 Acura TSX can vary by trim and lighting package, so the best approach is to compare the bulb in the car with the listing before ordering. This is especially important if your TSX uses halogen or HID components in different positions, or if you are considering aftermarket LED replacements. LED conversions may change beam pattern, brightness, or warning behavior, so choose bulbs carefully and make sure the base type matches. When possible, remove the installed bulb and check the number printed on it before purchase, since that is the most reliable way to confirm compatibility.
