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 |
Factory LED is where the industry went: it was 0% of the 2000s vehicles we hold specs for and it is 59% of the 2025-and-newer ones. Longer life is the upside; the tradeoff is that a failure is no longer a cheap bulb.
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) | LED | LED |
| High beam | 9005 | Halogen |
| Fog light | LED | LED |
| Front turn signal | LED | LED |
| Brake / tail | LED | LED |
| Rear turn signal | 7507 | Miniature |
| Reverse / backup | 921 | Miniature |
| License plate | LED | LED |
All trims have factory LED low beam, fog, front turn signal, brake/tail and license plate (non-replaceable). User-replaceable: 9005 high beam, 7507 rear turn signal, 921 reverse.
10th gen. Factory LED low beam is STANDARD on ALL trims including base LX (not user-replaceable). The only user-replaceable forward bulb is the 9005 high beam.
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 2018 Honda Accord take?
It uses a LED low-beam bulb and a 9005 high-beam bulb.
Can you replace the headlight bulb on a 2018 Honda Accord?
Before you shop: the 2018 Honda Accord has factory LED low beams, and on this vehicle they are not a replaceable bulb. The LEDs are built into the headlight assembly, so there is no part number to buy and no bulb to swap. If a low beam has failed, the fix is a new headlight assembly, which is an order of magnitude more expensive than a bulb and worth getting a diagnosis on first - LED headlights usually fail at the driver or a connector rather than at the diodes themselves, and that is often repairable.
