What to buy
This vehicle uses separate bulbs for low and high beam: 9005 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 | high beam | Halogen | a pair |
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 |
|---|---|---|
| High beam | 9005 | Halogen |
| Front turn signal | 3157 | Miniature |
| Brake / tail | 3157 | Miniature |
| Rear turn signal | 3157 | Miniature |
| Reverse / backup | 921 | Miniature |
| License plate | 194 | Miniature |
Low beam is 9012/HIR2 (halogen) or D3S (HID); 9012 not in standard short code set - set null. High 9005 confirmed by SEALIGHT and multiple aftermarket sources. Fog not confirmed across 2 sources for 2015+. 2022 halogen trim confirmed H11/9005 by some sources but conflicting.
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.
