Bulb size chart
This 1999 Acura TL bulb size page helps you quickly verify the correct bulb by lighting position, so you can replace a burned-out lamp without guessing. Whether you are changing a headlight, a parking light, or a small interior bulb, the chart below organizes the common fitments for this model year in one place.
The 1999 Acura TL used a mix of exterior, interior, and indicator bulb types, and the exact setup can vary by market, trim, and lighting package. Use this page as a practical reference for the bulb sizes listed for the 1999 TL, then match the position on your vehicle before buying replacements.
For best fitment, compare the bulb in your car with the listing on this page before ordering, especially if your TL has a different trim or a package-specific lighting setup. Some owners choose LED replacements for brighter output or longer life, but not every LED bulb will work correctly in every housing, and some may need polarity checks or load resistors. Aftermarket headlight conversions can also change the required bulb type, so confirm whether your car still uses the original halogen or HID-style setup. When in doubt, remove the installed bulb and read the base number directly before purchase.
