Fiat 500 F (1965-72) - Lighting
The lighting is an essential part of driving safety and ensures that the Fiat 500 is clearly visible by day and night. The original 6V or 12V bulbs often only offer limited light output, which prompts many owners to upgrade to brighter halogen bulbs or LED technology.
Important lighting components for the Fiat 500 F
1. main headlight
The original round headlights are a striking design element. Many owners upgrade to H4 halogen lamps or LED technology to improve visibility at night.
✅ Maintenance tip: If the light output is poor, earth points and plugs should be cleaned - often the problem is not the lamp, but corroded contacts.
2. rear lights & brake lights
The original rear lights with bulb technology tend to have contact problems due to corrosion on the sockets.
✅ Maintenance tip: A weak brake light can be caused by a faulty earth connection or a worn brake light switch.
3. indicators & hazard warning lights
The indicator contacts on the Fiat 500 are often a weak point. The indicator relays tend to malfunction, especially if they have corroded over the years.
✅ Maintenance tip: If the indicators work irregularly, the flasher unit, the earth contact and the flasher relay should be checked.
4. licence plate light & interior light
Often overlooked, but essential: non-functioning licence plate lighting can cause problems during the main inspection.
✅ Maintenance tip: If the interior light does not work, it is often due to a poor earth connection at the door contact switch.
