2017 Chevrolet Silverado 1500 bulb fitment starts with the headlights: both the low-beam and high-beam applications use a D5S bulb. The supplied fitment data does not identify a separate headlight bulb for these functions or indicate a projector/non-projector variation, so confirm the existing bulb and headlamp assembly before ordering.

- Rear brake and tail lights use 7444 bulbs.
- Rear turn signals and rear side markers use 7444NA bulbs.
- Reverse lights and the center stop light use 921 bulbs.
- Parking lights use 7443 bulbs.

No fog-light bulb is listed in the supplied fitment data. Match replacement bulbs by location and base type, particularly where the amber 7443A or 7444NA applications are specified.
