This page covers the 2019 Acura TLX and helps you verify bulb sizes by lighting position, so you can match the correct replacement before you buy. Whether you are checking exterior lights like the headlights, fog lights, brake lights, or turn signals, or interior bulbs such as map lights and the glove box light, the goal is to make fitment simple and reduce guesswork.
The 2019 Acura TLX uses a mix of LED lighting and a few replaceable bulb types depending on the lamp location. Because bulb fitment can vary by trim, package, market, and body style, it is important to confirm the exact position on the vehicle and compare it with the bulb chart before ordering parts.
For the best fit, always compare your vehicle’s installed bulb type with the listing for your specific trim and lighting package. Some positions on the 2019 TLX are LED assemblies, while others use serviceable bulbs such as 6615F, 168/917, 7440, 2721, or 158. If you are considering an aftermarket LED conversion, check polarity, bulb depth, heat management, and whether the housing is designed for LED use. Before purchasing, inspect the original bulb whenever possible, since previous repairs, regional differences, or option packages can change what is actually installed.
