Additional Notes

The Chevrolet Tracker uses two distinct dome light bulb sizes across its model years, the DE3022 and the DE3423, both of which follow ANSI standards applicable to the US and Canadian markets.
Both the DE3022 and DE3423 are festoon-type bulbs, a form factor characterized by a cylindrical body with metal end-cap contacts at each end rather than a base pin or wedge configuration.
The DE3022 and DE3423 operate at 12 volts, consistent with standard automotive electrical systems.
The primary physical difference between the two bulb types is length. The DE3022 measures 31mm, while the DE3423 measures 41mm, making them physically incompatible with each other despite sharing the same festoon contact style.
The Chevrolet Tracker (1999-2004) uses the DE3022 bulb for the dome light, covering the majority of the model's production span in this specification set.
The 1998 Chevrolet Tracker uses the DE3423 bulb for the dome light, which is the longer of the two festoon sizes listed.
Because the DE3022 and DE3423 differ in length by 10mm, substituting one for the other risks an improper fit within the dome light housing, as festoon bulbs rely on physical tension between their end caps and the fixture's contact springs.
