Acura RLX 2017 Bulb Size
Bulb size chart
This page covers bulb size information for the 2017 Acura RLX and is organized by lighting position so you can quickly verify the correct bulb for each exterior and interior location. Whether you are replacing a burned-out lamp or comparing your current setup before ordering, the goal is to make fitment easier to confirm.
The 2017 Acura RLX uses a mix of LED lighting and a few replaceable bulb types depending on the lamp location. Because trim and lighting package details can vary, it is important to match the bulb to the exact position on the vehicle rather than relying on a single size for the whole car.
For best results, compare the bulb listed for your RLX with the bulb already installed in the vehicle, especially if your car has a different trim, market specification, or lighting package. Some positions are LED assemblies, while others use serviceable bulbs, and aftermarket LED conversions may change fitment, brightness, or warning behavior. If you are unsure, remove the old bulb and check the base style before buying replacements.
