For the 2021 Jeep Grand Cherokee, headlight fitment depends on the installed headlamp configuration. The low beam uses either a D3S bulb or an H11 bulb, while the high beam uses either D3S or H9. Verify the existing headlight assembly and bulb type before ordering, since these options are not interchangeable.
Front fog lights use H11 or H11 LED, and the daytime running light is listed as H11. The front turn signal and parking light use 7444NA bulbs. For rear lighting, the brake light, tail light, and rear turn signal use 3157 bulbs. The center stop light, license plate light, and rear side marker are LED applications.
- Front side marker: 168 or LED, depending on configuration
- Step light: 906
- Courtesy light: 168
- Glove box light: 194
- Trunk light: 214-2
Several interior indicators, including the check, high-beam, instrument, park-brake, and turn indicators, use 74 bulbs.
