Ram ProMaster Fog Light Bulb Size

Additional Notes

• The H11 and H7 bulb types appear across the front fog light specifications for the Ram ProMaster, with H11 being the more frequently listed of the two across the model's year range.
• Both the H11 and H7 are single-filament halogen bulbs operating at 12V and 55W, meaning they share identical voltage and wattage ratings despite being distinct and non-interchangeable bulb types.
• The H11 uses a PGJ19-2 base, while the H7 uses a PX26d base. These bases are physically different, and one bulb cannot be substituted for the other without a change in the housing or socket.
• Both bulb types are governed by ECE standards, which originate in Europe and apply worldwide. Both also carry approval for use in the United States, and the H7 additionally holds approval in Japan.
• The Ram ProMaster lists H11 as the front fog light bulb for the 2014-2020 and 2022-2024 model years, with the exception of 2021, which lists H7.
• The 2021 Ram ProMaster is the only year in the specifications that lists exclusively H7 for the front fog light, without an H11 alternative.
• The 2018 and 2019 Ram ProMaster each list both H11 and H7 as front fog light bulb sizes, indicating that more than one hardware configuration was present in those model years.
