Fitment notes

For the 2018 Porsche 911, the high-beam headlight uses an integrated LED light source. Low-beam fitment varies by headlight configuration: some vehicles use LED, while others use a D3S bulb. Confirm the installed headlight type before ordering a replacement, since these options are not interchangeable.

Most exterior lighting is LED-equipped, including the front and rear turn signals, daytime running lights, parking lights, front and rear side markers, tail lights, brake lights, center stop light, reverse lights, and license-plate lights. The supplied data also lists LED dome, map, and glove-box lighting.

  • Step and interior lights: 2825 or 98, depending on the specific lamp.
  • Trunk light: 2886X.
  • Fog lights: No fitment is listed in the supplied data.

Check the existing lamp or vehicle lighting configuration when replacing the low-beam, step, or interior bulbs to ensure the replacement matches the original setup.
