- Rear turn signals use 7440A, while the brake lights use 7440R.
- Reverse lights use 921 bulbs.
- License plate lighting may use either 168 or 917 bulbs, depending on the lamp assembly.
- Tail lights, parking lights, front and rear side markers, the center stop light, and door-mirror lights are LED.

Confirm the existing bulb and socket before ordering where multiple sizes are listed, especially for the license plate and interior lighting.
