Where labor overlaps, replace bulbs in pairs so both sides age together, and put a smear of dielectric grease on the new socket contacts.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2021 Ford Expedition was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2021 Ford Expedition?
Every part on this page is matched to the 3.5L V6 Turbocharged engine. Then repeated bulb failure in one position usually means a socket or ground problem, not bad bulbs — replace the socket rather than chase it. The notes column carries position and trim qualifiers where they apply.
