Headlights for the 2021 Honda Pilot
This vehicle uses factory LED headlights on equipped trims. If one fails, the part is a headlight assembly, not a bulb, so it is usually a dealer or body-shop job rather than a DIY swap.

Can you replace it yourself?
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 |
| Front turn signal | 7440NA | Miniature |
| Brake / tail | LED | LED |
| Rear turn signal | 7440NA | Miniature |
| Reverse / backup | LED | LED |

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 2021 Honda Pilot take?
It uses a LED low-beam bulb and a 9005 high-beam bulb.
Is the 2021 Honda Pilot headlight bulb a DIY job?
The 2021 Honda Pilot has factory LED low beams. Factory LED headlights are often sealed into the assembly rather than being a serviceable bulb, so before you buy anything, check whether yours actually comes out. If it does not, the failure is at the assembly level, and it is worth having the driver and connectors checked before replacing the whole unit, because that is usually where LED headlights actually fail.
