2022 Toyota Highlander Bulb Sizes

Quick reference

The 2022 Toyota Highlander offers a blend of lighting technologies depending on the trim level. Lower trims such as the LE and XLE typically come equipped with halogen bulbs for many exterior lighting functions. As you move up to trims like the Limited and Platinum, you'll find more advanced LED lighting systems, particularly for headlights, daytime running lights (DRL), and tail lights.

For the low beam and high beam headlights, most LE and XLE models will use H11 for low beams and 9005 for high beams. These are conventional halogen bulbs. However, the higher trim levels come with factory LED projectors for both low and high beams, offering superior illumination and a distinctive modern look. Fog lights on halogen-equipped Highlanders are typically H16, while LED fog lights are integrated units on premium trims. The DRLs can vary significantly; some LE/XLE models might integrate the DRL function into the high beam bulb (operating at a lower wattage), while higher trims feature dedicated, brighter LED DRL strips.

Turn signals, both front and rear, commonly use WY21W amber halogen bulbs across many trims. Brake lights and tail lights on most 2022 Highlanders are integrated LED assemblies, meaning individual bulbs are not replaceable, but rather the entire unit would need replacement if a segment fails. Reverse lights generally utilize a W16W halogen bulb. License plate lights and front side markers are typically W5W halogen bulbs, while the rear side markers are usually integrated LEDs.

Inside the cabin, the lighting can also vary. Dome lights might be a 31MM fuse-style bulb (also known as a festoon bulb) on lower trims, while higher trims feature LED dome lighting. Map lights often use a 168 halogen bulb on some models, with LED options available on others.

LED vs halogen upgrade considerations

Upgrading your 2022 Toyota Highlander's halogen bulbs to LED can dramatically improve visibility and modernize its appearance. However, there are several factors to consider. When replacing halogen headlights (H11, 9005) with LED equivalents, you might encounter CANBUS errors, which manifest as flickering lights or
