This 2016 Acura TLX bulb size page helps you verify the correct bulb type by lighting position, so you can match the right replacement to the exact lamp on your car. Whether you are replacing an exterior signal light or a small interior bulb, checking by location is the easiest way to avoid ordering the wrong part.
The 2016 Acura TLX uses a mix of LED lighting positions and a few conventional bulb types, and fitment can vary by trim, package, market, and body style. Use this page as a position-by-position guide for headlights, tail lights, turn signals, interior lights, and other lamps before you buy replacements.
For best results, confirm the installed bulb before purchasing, especially if your TLX has been modified or if you are comparing halogen and LED setups. Some lighting positions may be factory LED on one trim and different on another, and aftermarket LED conversions can change the bulb style or require additional hardware. If you are replacing a bulb that is not listed with an exact part number here, remove the old bulb and match the base, connector, and size carefully before ordering.
