2000 Porsche 911 Headlight Bulb Size
The 2000 Porsche 911 uses a D2S low-beam and a H7 high-beam headlight bulb.
Key takeaways
- Low beam: D2S. High beam: H7.
- The D2S low beam is HID (xenon), not halogen - it runs through a ballast at high voltage, so it is a replaceable bulb but not a casual swap.
- Fog, signal, and reverse bulbs use different sizes - check each before buying.
- Reverse / backup
- 7506
- License plate
- 6418
Where to buy bulbs for the 2000 Porsche 911
Headlight bulbs dim over time, so replace them in pairs even if only one has failed. HID bulbs run through a ballast at high voltage, so this is a replaceable bulb but not a casual swap - disconnect the battery first. To order the exact sizes online:

What to buy
This vehicle uses separate bulbs for low and high beam: D2S for the low beam, and H7 for the high beam. They are different parts, so check which one has actually failed before buying. Replace them in pairs regardless. Bulbs from the same batch age at the same rate, so when one goes the other is usually close behind, and a fresh bulb beside a tired one is visibly brighter and unevenly aimed. Doing both at once costs a few dollars more and saves doing the job twice.
| Bulb | Covers | Type | Buy |
|---|---|---|---|
| D2S | low beam | HID | a pair |
| H7 | high beam | Halogen | a pair |
D2S is a widely used headlight bulb, fitted to 3.6% of the vehicles we hold specs for. Any parts store will have it, and you are not restricted to the dealer.
Every bulb on this vehicle
Headlights get the attention, but the small bulbs are what fail an inspection. A burnt-out brake or turn bulb is also the cheapest ticket you will ever get, and most of these are a few dollars and a twist to change.
| Position | Bulb | Type |
|---|---|---|
| Low beam (headlight) | D2S | HID |
| High beam | H7 | Halogen |
| Reverse / backup | 7506 | Miniature |
| License plate | 6418 | Miniature |
996/997: factory HID D2S low beam; halogen H7 high beam. Brake/tail/rear turn are assembly units not serviceable bulbs. Halogen-equipped 996s use H7 low beam instead of D2S.
Why this keeps getting harder
Headlight bulbs used to be a commodity: a handful of codes covered most cars and any of them cost a few dollars. That is ending. Across the vehicles we hold specs for, factory LED low beams went from 0% of 2000s cars to 59% of 2025-and-newer ones. LEDs last far longer, which is the upside and a real one. The tradeoff is that when they do fail, it is often not a bulb you can buy at all, and the fix moves from a $20 part to a headlight assembly.

Frequently asked
What headlight bulb does a 2000 Porsche 911 take?
It uses a D2S low-beam bulb and a H7 high-beam bulb.
Is the 2000 Porsche 911 headlight bulb a DIY job?
The 2000 Porsche 911 uses D2S HID (xenon) low beams. This is a real bulb you can replace, but it is not a casual swap: HID runs through a ballast at several thousand volts to strike the arc, so disconnect the battery first and never handle a live system. Replace them in pairs - xenon bulbs shift colour as they age, and a new one next to an old one is obvious. Do not touch the glass with bare fingers.
Is D2S a common headlight bulb?
D2S is a widely used headlight bulb, fitted to 3.6% of the vehicles we hold specs for. Any parts store will have it, and you are not restricted to the dealer.
