Our catalog currently lists 104 electrical bulb & socket parts for the 1975 Fiat 128 across 10 subcategories and 10 brands, covering the 1.3L L4 engine. Each part is matched to the engine(s) it fits.
What are the signs of electrical bulb & socket problems on a 1975 Fiat 128?
Common symptoms include a lamp that flickers over bumps, melted or discolored socket plastic, or bulbs that keep failing early on one side. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
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 1975 Fiat 128 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 1975 Fiat 128?
Every part on this page is matched to the 1.3L L4 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.
