Ram ProMaster Map Light Bulb Size

Additional Notes

• The 562 bulb is the sole map light bulb type listed across all Ram ProMaster model years in these specifications.
• The 562 is a festoon-style bulb, meaning it is cylindrical in shape with flat metal end-cap contacts at each end rather than a base socket.
• The 562 bulb has a nominal length of 44mm, which is the critical fitment factor for festoon bulbs, as the housing span between the two contact points must match this length.
• The 562 operates at 12 volts and draws 12 watts, placing it within the standard low-wattage range typical of interior courtesy and map lighting applications.
• The 562 conforms to ANSI standards and is recognized in both the United States and Canada, indicating a standardized specification rather than a proprietary or regional-only part.
• The Ram ProMaster (2018) specification designates the 562 bulb specifically for the Front Center position, distinguishing it from other potential map light locations within that model year.
• The 44mm festoon length is a hard fitment requirement. Festoon bulbs of differing lengths, such as 31mm, 36mm, or 41mm variants, are not interchangeable even if they share the same voltage and wattage ratings.
• The end-cap contact design of the 562 means it is incompatible with wedge-base or bayonet-base sockets, as those socket types require a physically different bulb termination.
