Additional Notes

The 211-2 is the sole dome light bulb size listed across all model years of the Dodge Omni covered by these specifications.
The 211-2 follows the ANSI standard, meaning it conforms to a recognized North American specification for automotive lighting used in both the United States and Canada.
The 211-2 is a festoon-type bulb, a cylindrical form factor held in place by spring clips at each end rather than a screw or bayonet base.
The bulb measures 41mm in length, which is the critical fitment factor for festoon bulbs, as the spring-clip housing must match this span precisely.
The 211-2 uses an SV8.5 base, a designation that refers to the 8.5mm width of the metal end caps on the festoon body.
The bulb operates at 12 volts and draws 12 watts, consistent with standard 12V automotive electrical systems.
The Dodge Omni uses the 211-2 across the 1978-1984 and 1989-1990 model years listed in these specifications.
Because the 211-2 is an ANSI-standardized part, bulbs carrying this designation from different manufacturers share the same voltage, wattage, base type, and length, which governs direct interchangeability.
