The 2019 Toyota Highlander uses different headlight bulbs depending on the trim and headlight system. In most cases, halogen headlights use H11 for low beams and 9005 for high beams, while LED-equipped models rely on integrated LED modules rather than replaceable bulbs.
Halogen headlights (most trims)
Most 2019 Highlanders with halogen headlights follow a standard bulb lineup for replacement.
- Low beam: H11
- High beam: 9005 (HB3)
- Fog lights (if equipped): H11
Note: Fog light bulb types can vary by market or specific vehicle configuration, so always verify with the owner's manual if you’re unsure.
LED headlights (higher trims)
On higher trims that come with LED headlights, the design uses integrated LED modules rather than interchangeable bulbs. In these systems, you typically do not replace a traditional bulb; service often involves the entire headlight assembly or LED module, sometimes under warranty or via a dealer for component replacement. Some aftermarket upgrades exist, but they must be compatible with the Highlander’s CAN-bus system and lighting design.
How to confirm your exact bulb type
To determine the exact bulb type for your specific Highlander, follow these steps.
- Consult the owner’s manual for the exterior lighting section and bulb specifications for your trim.
- Inspect the headlight area: remove the access panel or cap and read the bulb type stamped on the bulb itself, if accessible.
- Look for a label near the headlamp or on the radiator support that lists bulb types for your vehicle.
- If uncertain, use Toyota’s official parts lookup or contact a Toyota dealer with your Vehicle Identification Number (VIN) to confirm the exact bulb configuration.
With the confirmed bulb type, purchase from an authorized retailer to ensure compatibility and maintain warranty coverage.
Summary
For 2019 Toyota Highlander, halogen headlights typically use H11 low beams and 9005 high beams, with H11 for fog lights if equipped. LED-equipped models use integrated LED modules, making bulb replacements uncommon and often requiring swap of the entire headlight unit or module. Always verify the exact configuration for your trim via the owner’s manual, on-vehicle labels, or a dealer/parts lookup to ensure you choose the correct replacement.
