Bulb size chart
This 2003 Acura TL bulb size guide helps you verify the correct replacement bulb by lighting position, so you can match the right part before you buy. Whether you are replacing a headlight, interior lamp, or rear signal bulb, this page is organized to make fitment checks quick and simple for the 2003 Acura TL.
Use the bulb chart to compare each light location on the vehicle with the listed bulb type. The 2003 Acura TL uses different bulbs for exterior lighting, cabin lighting, and dashboard indicators, so checking the exact position matters before ordering replacements.
Fitment can vary by trim, lighting package, market, and body style, so it is smart to confirm the bulb already installed in your Acura before purchasing. Some positions may be listed with halogen or LED replacement options, especially for fog lights, but aftermarket conversions do not always fit or perform the same as factory bulbs. If you are switching from halogen to LED, check connector style, housing clearance, beam pattern, and local lighting rules. For the most reliable result, compare the old bulb number, inspect the socket, and verify the installed bulb before you order.
