Acura TSX 2014 Bulb Size
Bulb size chart
This 2014 Acura TSX bulb size guide helps you verify the correct bulbs by lighting position, so you can match the right part before you buy. Because Acura used different lighting setups by trim, body style, and market, it is important to confirm the exact bulb type for each exterior and interior location on your TSX.
Use this page as a quick reference for common replacement points such as headlights, fog lights, tail lights, brake lights, turn signals, license plate lights, dome lights, map lights, and cargo-area bulbs. The 2014 Acura TSX may use different bulbs for sedan and wagon applications, so checking the position-specific listing is the best way to avoid ordering the wrong part.
For best fitment, compare the bulb chart with your exact TSX trim and lighting package before purchasing. Some positions may use halogen bulbs, while others may be LED or have LED-style assemblies, and aftermarket conversions can change the required bulb type or connector fit. If your car has been modified, or if you are unsure whether a previous owner installed non-original bulbs, remove the installed bulb and check it directly before ordering replacements.
