Typically, the low beams on a 2016 Highlander use H11 bulbs and the high beams use 9005 bulbs; fog lights, if your trim has them, usually use H11 as well. Note that trims with HID or LED headlights differ and may require different replacements.
Bulb types by function
For most North American market Highlanders with halogen headlights, the following sizes apply:
- Low beam: H11 (55W)
- High beam: 9005 (HB3) (65W)
- Fog lights: H11 (55W) – if your vehicle is equipped with fog lamps
These are typical for the standard halogen setup. Regions and trims may vary, so verify against your exact vehicle configuration.
Variations by trim or region
Some Highlanders are equipped with HID or LED headlights from the factory or via optional packages. In those cases, the replacement approach changes: you may not use H11/9005 bulbs, and you could need HID bulbs, ballast modules, or entire headlight assemblies. Always confirm using the manual, the headlight label, or your dealer.
How to confirm the exact bulb in your vehicle
To ensure you buy the correct bulb, use these verification steps before purchasing:
- Check the owner’s manual section on headlights for the recommended bulb types by function.
- Inspect the bulb currently installed in the headlight and read any markings (such as H11 or 9005) on the glass or base.
- Look for a label on the headlight housing or remove the bulb cap to read part numbers printed on the old bulb.
- If in doubt, contact a Toyota dealer or a trusted parts retailer and provide your VIN or trim to confirm compatibility.
Verifying the exact trim and region will help you avoid buying the wrong bulb. If your Highlander has HID/LED headlights, you’ll likely need a different replacement approach.
Summary
For the common 2016 Toyota Highlander with halogen headlights, plan for H11 low beams and 9005 high beams, with H11 for fog lights if equipped. Confirm any variations by checking your manual, the headlight housing labels, or with a dealer, especially if your vehicle uses HID or LED headlights or has a different regional configuration.
