Dodge Lancer Dome Light Bulb Size

Additional Notes

• The Dodge Lancer dome light specifications cover model years 1956-1962 and 1985-1989, with three distinct bulb types appearing across those periods.
• The 211-2 is a festoon-style bulb with an SV8.5 base and a 41mm length, rated at 12V and 12W under the ANSI standard applicable to the US and Canada.
• Festoon bulbs are held in place by spring-loaded contacts at each end of the bulb body rather than by a base socket, which is a defining characteristic of the SV8.5 fitting used by the 211-2.
• The Dodge Lancer (1986-1989) uses the 211-2 for the dome light, making it the most consistently specified bulb across the years covered in these records.
• The 912 is a T15 wedge-type bulb rated at 12V and 12W, and it is noted as a variant of the 921, meaning the two share closely related electrical and physical characteristics though they are not identical.
• The 1985 Dodge Lancer uses the 912 wedge bulb for the dome light, which differs in base type from the 211-2 used in the four subsequent model years, indicating a fitment change between 1985 and 1986.
• The 1004 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a 21/5W output reflecting its two separate filaments operating at different wattages.
• The 1004 is listed as a variant of the 1157, a widely recognized automotive bulb, though the two are not directly interchangeable without confirming that voltage and wattage ratings are compatible with the specific application.
• The Dodge Lancer (1956-1962) uses the 1004 for the dome light across all specified model years in that era, with the BAY15d bayonet base representing a physically distinct fitment from both the festoon and wedge types used in later years.
• Because the three bulb types across these specifications use different base designs, namely festoon, wedge, and bayonet, none of them are physically interchangeable with one another regardless of voltage or wattage similarities.
