Acura TSX 2011 Bulb Size
Bulb size chart
This 2011 Acura TSX bulb size guide helps you verify the correct bulbs by lighting position, so you can match the right fit before you buy. Because Acura used different lighting setups depending on body style, trim, and market, it is important to confirm the exact bulb type for each lamp on your TSX.
Use this page to check common exterior and rear lighting locations such as headlights, fog lights, brake lights, turn signals, parking lights, reverse lights, license plate lights, and the center high mount stop light. The 2011 Acura TSX uses a mix of halogen, HID, and LED-related applications, so identifying the bulb by position is the safest way to avoid ordering the wrong part.
Fitment can vary with trim package, factory lighting equipment, and whether your 2011 TSX is a sedan or wagon, so always compare the bulb listed here with the one already installed in your vehicle. Some positions may use halogen bulbs while others may be HID or LED-related, and aftermarket LED conversions can change the required bulb type, base, or connector style. If you are replacing a bulb for the first time, it is a good idea to remove the old bulb and check the markings on the glass or base before purchasing a replacement, especially for fog lights and headlight applications.
