Bulb size chart
If you need bulb size information for the 2001 Acura TL, this page is designed to make the lookup quick and simple. It organizes the lighting positions by location so you can verify the correct bulb size before you buy, whether you are replacing a headlight, tail light, turn signal, or license plate bulb.
The 2001 Acura TL uses different bulb types depending on the lamp position, and some lighting equipment can vary by market and body style. Use this page to match each bulb to its specific function, so you do not confuse the high beam, low beam, parking light, or rear signal bulb with another socket on the car.
Fitment can vary by trim, lighting package, and regional specification, so it is smart to confirm the bulb already installed in your 2001 Acura TL before ordering replacements. Halogen bulbs and LED replacements are not always direct swaps, especially when beam pattern, polarity, or heat management matters. If you are considering an aftermarket LED conversion, check whether the housing and socket are designed for it, and remember that some upgrades may not perform the same as the original halogen or HID setup. The safest approach is to compare the installed bulb, the socket style, and the vehicle’s lighting configuration before purchase.
