Acura TL 2012 Bulb Size

Bulb size chart

This 2012 Acura TL bulb size guide is designed to help you verify the correct bulb by lighting position, so you can quickly match the right replacement for headlights, brake lights, interior lamps, and other exterior and cabin lights. Because Acura used different lighting setups depending on trim, package, market, and body style, checking the exact location on the vehicle is the best way to confirm fitment before you buy.

Use this page as a practical reference for the 2012 Acura TL when replacing a burned-out bulb or upgrading a light. The chart covers common positions such as low beam, high beam, fog lights, license plate lights, map lights, dome lights, reverse lights, and more, making it easier to narrow down the correct bulb size for each lamp on the car.

For the best fit, compare the bulb listed for your lighting position with the bulb already installed in your Acura TL, especially if your car has a premium lighting package or a market-specific setup. Some positions use LED assemblies, while others use halogen or HID-style bulbs, so do not assume every lamp can be swapped with a direct LED replacement without checking compatibility, polarity, and housing space. Aftermarket LED conversions may require additional parts or may not perform the same as the original bulb, especially in headlight and fog light applications. If you are unsure, remove the old bulb first and confirm the base type and markings before ordering.
