- 2021-2025 Toyota Sienna with matching front bumper fog-light openings
- Factory fog-light reference applications use the 2.5L hybrid Sienna platform; trim/package equipment should be confirmed
Product Overview
If a Sienna was not built with fog lights, adding them requires more than mounting two lamps in the bumper. The switch circuit, fused power feed, relay/harness routing, and bumper openings all need to be correct or the lights may flicker, stay on, or fail to operate.
Toyota's factory LED fog lamps use 81210-08040 on the right and 81220-08040 on the left in equipped 2021 Sienna applications. This aftermarket kit includes its own wiring and switch, so it should be treated as a conversion package rather than a plug-in replacement for every factory fog-light configuration.

Compatibility Notice
Factory Sienna fog-light equipment varies by trim and parking-assist package. This kit uses its own harness/switch and should not be assumed to plug directly into every factory connector.
Frequently Asked Questions
Q: What should I check before replacing the lamp? A: Check the fuse, power, ground, connector, bulb or LED module, and obvious wiring damage so an electrical fault is not mistaken for a bad housing.
Q: How do I confirm the correct version? A: Match year/body style, position, connector, lighting technology, mounting points, and the OE/reference number when available.
