  • Read the notes on each row for position, trim and spec qualifiers before you order.
  • Where labor overlaps, replace bulbs in pairs so both sides age together, and put a smear of dielectric grease on the new socket contacts.
  • Cross-reference the manufacturer part number against your old part or a service-manual listing.

What are the signs of electrical bulb & socket problems on a 1972 Fiat 850?

What should I replace at the same time?

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 1972 Fiat 850 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 1972 Fiat 850?
