Additional Notes

The Saab 9-3 glove box uses two distinct festoon bulb types across its model years: the DE3423 for 2007-2011 and the 6411 for 1999-2006.
Both the DE3423 and 6411 are festoon-type bulbs, meaning they are cylindrical lamps that mount horizontally between two end contacts within a fixed housing.
The DE3423 is an ANSI-standardized bulb rated at 12V and measures 41mm in length, with end-cap contacts that make electrical connection at each tip of the bulb body.
The 6411 is also an ANSI-standardized 12V festoon bulb, rated at 5W, with an SV8.5 base and a 36mm length.
The DE3423 and 6411 are not interchangeable in the Saab 9-3 glove box, as the two bulbs differ in length by 5mm and use different base configurations.
The SV8.5 base designation on the 6411 refers to a specific festoon base standard where the 8.5 indicates the contact width in millimeters, a detail absent from the DE3423 specification.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating standardized physical and electrical tolerances shared across compatible fixtures from multiple manufacturers.
