For the 2017 Dodge Viper, both the low-beam and high-beam headlights use D3S bulbs. The supplied fitment data does not indicate a separate bulb option by headlight type or configuration, so verify the existing bulb and housing before ordering.
Several exterior lighting functions are LED-equipped rather than using replaceable conventional bulbs. These include the front turn signals, daytime running lights, parking lights, rear turn signals, tail lights, brake lights, center stop light, reverse lights, license plate lights, and step lights.
- Front side marker: 2821
- Rear side marker: 2821
- Ash tray light: 37
- Instrument illumination: 103
- Trunk light: 168 or 917
No fog-light bulb is listed for this model-year fitment. For LED-equipped locations, replacement may involve an LED assembly or vehicle-specific service procedure rather than a standard plug-in bulb.
