This page helps you find the correct bulb sizes for the 2004 Acura TL by lighting position, so you can match the right bulb to the right socket before you buy. Whether you are replacing an exterior lamp or a small interior bulb, checking the location first is the easiest way to avoid ordering the wrong part.
The 2004 Acura TL uses a mix of halogen, HID, and LED-style lighting depending on the lamp location and equipment. Because trim and lighting package can vary by market and body style, this year page is meant to help you verify the bulb size for each specific position on the car, from headlights and DRLs to map lights and license plate lights.
For the best fitment, compare the bulb listed here with the bulb already installed in your Acura TL before purchasing, especially if your car has been modified or converted to LED. Some positions may differ by trim, package, or regional specification, and aftermarket housings or retrofit kits can change the required bulb type. If you are switching from halogen to LED, make sure the replacement is compatible with the socket, polarity, and available space, and remember that some lighting functions may need additional parts or resistors to work correctly. When in doubt, verify the installed bulb number and connector style first.
