Vehicle names and OE references identify compatibility only. This is an aftermarket replacement, not a vehicle-brand genuine part.
Use protective gloves, compare backing plate and clips, connect only matching contacts, and test the blind-spot icon before final seating.
Availability is specific to the selected SKU and warehouse. A left-and-right pair is a separate order unit; it is not automatically assembled from single-side stock. U.S. replenishment, factory bulk supply, freight and lead time are reviewed separately.
For repair-shop, reseller or recurring purchases, use the product’s trade-quote button to send the selected SKU and quantity. We confirm fitment, availability and written pricing before the order. Explore our Wholesale & Trade Program.
