What should I replace at the same time?
Where labor overlaps, replace the retaining clips and fasteners with any panel or trim job — reused clips are the usual cause of rattles afterwards.
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 Freightliner B2 was originally sold in the US, the safest choice is a part marked for the US market.

Then check whether a lamp assembly is a capsule-only replacement or a full housing before ordering — they are very different jobs and the part numbers look similar. The notes column carries position and trim qualifiers where they apply.
