Ram C/V high beam and low beam headlight bulbs both utilize H11 size bulbs for proper illumination. Replacement chart data covers 2012 through 2015 vehicle production specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ram C/V uses the H11 bulb size for both high beam and low beam headlights across the 2012-2015 model years.
The H11 is a single-filament halogen bulb operating at 12 volts and 55 watts, mounted on a PGJ19-2 base.
Because the Ram C/V shares the same H11 specification for both high and low beam positions, the same bulb type fits either socket, though each position remains a separate physical installation.
The H11 bulb conforms to ECE standards, which govern lighting equipment across Europe and many other markets worldwide, and it also carries approval for use in the United States.
The PGJ19-2 base is a keyed, twist-lock connector specific to the H11 and a small number of related bulb types; it is not interchangeable with the physically similar PGJ19-1 base used by the H8, or the PGJ19-3 base used by the H9, despite those bulbs sharing the same general housing shape.
The H9 bulb, which uses the PGJ19-3 base and operates at 65 watts, is sometimes used as a high-output substitute in H11 sockets, but doing so exceeds the original 55-watt specification and may affect socket and wiring integrity over time.
