The following are the bulbs recommended by Fiat for each location on the car. US/Canada/Mexico/Latin America specifications are all included.

I have to admit - headlight bulb numbering is a dumpster fire. There are multiple specifications, and in some cases, multiple ones that meet the specs below and some confusion between sources on which bulb goes in which location. So if anyone finds any errors, please let me know.

Front Fog - H11 55W
Rear Turn Signal - PY21W
Backup - 921
Brake / Tail - P21 5W

Third Brake - Cabrio - Integrated LED

Front Park (US/Can) - W21 5W
Front Side Marker - W3W / 12256
Front Turn Signal (Mexico / Latin America) - PY21W

Headlamp High Beam (Mexico/Latin America) - H7
