Volvo 142 Dome Light Bulb Size

Additional Notes

• The Volvo 142 dome light specifications span the 1967-1974 model years, with three distinct bulb types appearing across that range: the 1895, DE3423, and 211-2.
• The 211-2 is the most frequently specified bulb in the Volvo 142 dome light data, appearing in the 1967-1968 and 1970-1971 model years.
• The 211-2 is an ANSI-standard festoon bulb rated at 12V and 12W, with a 41mm length and an SV8.5 base, which uses a bayonet-style socket mount rather than simple end-cap pressure contacts.
• The DE3423 also appears across multiple model years, specifically 1969, 1972, and 1973, making it the second most recurring bulb type in these specifications.
• The DE3423 is an ANSI-standard festoon bulb with a 41mm length that relies on end-cap contacts for its electrical connection, distinguishing its socket fitment from the SV8.5-based 211-2 despite both sharing the same 41mm length.
• Because the DE3423 and 211-2 share a 41mm length but differ in base type, the two bulbs are not interchangeable, and substituting one for the other in a Volvo 142 would require a socket that matches the specific base design.
• The 1895 is specified only for the 1974 model year and represents a fundamentally different bulb category from the festoon types used in all prior years, as it is a miniature wedge bulb of the T5 form factor.
• The 1895 wedge bulb operates at 12V with a wattage of only 0.9W, a notably lower output than the 12W rating of the 211-2, reflecting a different design intent or socket configuration in the 1974 model year.
• All three bulb types carry ANSI standard designations valid for the US and Canadian markets, indicating standardized ratings and physical specifications recognized across those regions.
• The shift from festoon-type bulbs in 1967-1973 to the T5 wedge format in 1974 reflects a change in socket architecture between model years, meaning dome light hardware from earlier Volvo 142 models would not accept the 1895 wedge bulb without modification.
