Fiat 850 (1964-1973) - Lighting
The lighting on the Fiat 850 was modern for its time, but today the round headlights and tail lights often have contact problems due to outdated wiring.
Important lighting elements for the Fiat 850
1. main headlights & dipped beam
The headlights were powerful by the standards of the time, but the original Bilux lamps only provided weak light.
✅ Tip: Converting to H4 headlights significantly improves visibility at night.
2. indicators & brake lights
The rear lights of the Fiat 850 are prone to mass problems, which cause the indicators and brake lights to function unreliably.
✅ Tip: If one tail light appears darker than the other, the earth connection should be checked and replaced if necessary.
