2019 Acura RDX bulb fitment is LED-based for the primary exterior lighting. The low-beam and high-beam headlights are listed as LED, so this fitment data does not specify a conventional replaceable halogen bulb size. The fog lights are also LED.
Several other exterior lamps use LED assemblies, including the front turn signals, daytime running lights, parking lights, front and rear side markers, tail lights, brake lights, center stop light, reverse lights, license-plate lights, door-mirror lights, and trunk light. No projector or non-projector headlight distinction is provided, so confirm the original lamp assembly before ordering replacement parts.
- Rear turn signal: 7507
- Glove-box light: 2721
- Interior lighting: 194 and 7441 applications are listed
- Vanity light: 6615F
- Dome and map lights: LED
Because the headlamps and most exterior lighting are identified as LED, verify whether the complete lamp assembly or an LED-specific replacement is required for the exact repair.
