For the 2020 Mazda CX-9, both the low-beam and high-beam headlights use LED lighting. The fog lights, daytime running lights, brake lights, center stop light, tail lights, and rear side markers are also LED.
Front lighting varies with the vehicle’s adaptive-lighting configuration. Models with adaptive lighting use LED front turn signals, parking lights, and side markers. Without adaptive lighting, these positions use 7440A front turn signals and 2827 parking and side-marker bulbs. The rear turn signals use 7440A bulbs, while the reverse lights use 921 bulbs.
- License plate lighting: 2825 or 98
- Dome, map, and trunk lights: DE3175
Verify whether the CX-9 has adaptive lighting before ordering front turn-signal, parking-light, or front side-marker replacements, since the listed fitment changes by configuration.
