Additional Notes

The Plymouth Laser dome light specifications cover model years 1990-1994 and reference two distinct festoon bulb types: the DE3022 and the 211-2.
A festoon bulb is a cylindrical lamp that mounts horizontally between two spring-loaded end contacts or a base socket, a form factor common in automotive interior lighting.
The 211-2 bulb is specified for the Plymouth Laser across 1990-1992, making it the more frequently referenced of the two bulb types in these specifications.
The 211-2 operates at 12V with a 12W power rating and measures 41mm in length, using an SV8.5 base for its socket connection.
The DE3022 is specified for the 1994 Plymouth Laser and operates at 12V with a 31mm length, using end-cap contacts rather than a dedicated base socket.
The DE3022 and 211-2 are both ANSI-standard bulbs rated for use in the United States and Canada, though they are not interchangeable due to their differing lengths and contact types.
The 41mm length of the 211-2 versus the 31mm length of the DE3022 represents a meaningful physical difference that affects housing fitment, as festoon bulbs must span the exact distance between their mounting contacts.
The SV8.5 base designation on the 211-2 refers to a specific festoon base width of 8.5mm, which determines socket compatibility independently of the bulb's overall length.
