This page covers the 2019 Acura RLX and helps you verify the correct bulb size by lighting position. Instead of guessing from a single “headlight” or “tail light” listing, you can match the bulb to the exact location on the car, which is especially useful on a model with multiple LED and non-LED variations.
The 2019 RLX uses a mix of LED lighting and a few conventional bulb types depending on the lamp location and configuration. That means the correct replacement can differ for the headlight, fog light, interior lamps, license plate lights, and rear lighting, so checking the position-specific chart is the best way to confirm fitment before ordering.
Fitment can vary by trim, lighting package, market, and body style, so always compare the bulb position on your vehicle with the chart on this page. Some 2019 Acura RLX applications use LED assemblies, while others may use halogen-style bulbs or different original-equipment options, especially for parking lights, turn signals, and backup lights. If you are considering an aftermarket LED conversion, make sure the bulb base, polarity, and housing clearance are compatible, and remember that a conversion bulb may not match the original beam pattern or light output. Before buying, it is smart to remove the installed bulb and verify the base number and connector style, since the same model year can have more than one valid fitment depending on equipment.
Yes, the chart shows LED headlight listings for the 2019 Acura RLX, including separate high beam and low beam entries. Some pages may also list a combined high beam and low beam LED application depending on the lighting setup.
The front fog light bulb is listed as LED on this page. Because the fog lamp is part of an LED setup, you should match the exact lamp position rather than assume a standard replaceable halogen bulb.
Yes. The daytime running light bulb is listed as LED for the 2019 RLX, so the correct replacement depends on the specific LED lamp assembly used on the vehicle.
The license plate light bulb is listed as LED. That means the license plate lamp on this model is not treated like a standard incandescent bulb replacement on this chart.
The brake light bulb is listed as LED for the 2019 Acura RLX. If you are replacing a rear lamp issue, confirm whether the problem is the LED assembly itself or another related lighting component.
The tail light bulb is listed as LED. On the 2019 RLX, rear lighting can have multiple functions, so it is important to match tail light, brake light, and turn signal positions separately.
Yes. The chart shows multiple turn signal listings, including LED options and alternative original-style bulb entries such as 1157A and 7440 for certain positions. This is why checking the exact front or rear location matters before purchase.
The page shows LED backup light listings as well as an alternative original-style 921 bulb option for one configuration. Because more than one fitment appears, you should verify the installed bulb or the lamp housing before ordering.
The trunk or cargo area light is listed as 168 or 917. Either of those bulb numbers may apply depending on the specific lamp setup in the vehicle.
The vanity mirror light bulb is listed as 24. If the mirror light is out, confirm the bulb base and access method before replacing it.
Yes. The chart includes LED listings for the dome light, map light, glove box light, and stepwell light, which helps you identify the correct interior bulb by location.
Because trim, package, and market differences can change the original equipment lighting. Some positions may have LED assemblies on one version and different bulb numbers on another, so the chart includes the available fitment rows for comparison.
Yes. Even with a model-specific chart, checking the installed bulb is the safest way to confirm fitment, especially for positions with multiple options like parking lights, turn signals, and backup lights.
