- Front turn signals use 3457AK, while front parking lights use 3457A.
- Rear turn signals use 12496; reverse and brake lights use 7506.

- License plate and vanity lights use 6418; the dome light uses 6411.
Match the bulb location and base style when replacing a lamp, particularly where similar-looking 3457-series bulbs are specified for different front-light functions.
