What to buy
This vehicle uses separate bulbs for low and high beam: 9005 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 |
|---|---|---|---|
| 9005 | low beam | Halogen | a pair |
| H7 | high beam | Halogen | a pair |
9005 is a widely used headlight bulb, fitted to 2.8% 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) | 9005 | Halogen |
| High beam | H7 | Halogen |
| Fog light | H7 | Halogen |
| Front turn signal | 1157 | Miniature |
| Brake / tail | 1157 | Miniature |

| Reverse / backup | 1157 | Miniature |

Should you upgrade to LED?
The obvious question is whether you can drop an LED into a 9005 halogen housing. Physically, usually yes, and the kits are everywhere. Whether you should is a different matter, and it comes down to your housing. A projector housing has a lens and a cutoff shield that keeps light on the road, and a well-made LED in a projector is generally fine. A reflector housing aims light using the bowl geometry, which was designed around the exact position and shape of a halogen filament. An LED does not put light in the same place, so the reflector scatters it - you get more glare for oncoming traffic and often less usable light on the road, while your own view feels brighter because the source is whiter. Look at your housing before you buy: if you can see a lens, you have a projector. Note too that DOT-compliant LED replacements for halogen housings are rare, which is a legality issue in some states and an inspection issue in others.
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.
