2019 Chevrolet Volt bulb fitment starts with LED low-beam headlights and 9005 high beams. The low beams are listed as LED, so confirm the vehicle’s original headlamp assembly before ordering a replacement; the supplied fitment data does not indicate a separate replaceable low-beam bulb size. The high beam uses a 9005 bulb.
- Front turn signals and parking lights use 7444NA bulbs.
- Rear turn signals use 7440A, while reverse lights use 7440.
- Brake lights use 7443R bulbs. The center stop light, tail lights, and rear side markers are LED.
- License plate lighting may use either 2825 or 98 bulbs.
- Trunk lighting may use 194 or 7441 bulbs, and the vanity light uses 7065.
Because several exterior lamps are LED, replacement options may depend on the original lamp assembly rather than a conventional bulb socket. Verify the existing bulb or housing when servicing the license plate and trunk lights, where more than one fitment is listed.
