Additional Notes

The Suzuki Forenza uses the DE3425 bulb for the dome light across all listed model years, spanning 2004-2008.
The DE3425 is an ANSI-standard bulb, meaning it conforms to a standardized specification recognized in both the United States and Canada.
This bulb follows the festoon design, a cylindrical form factor in which the bulb makes electrical contact through metal caps at each end rather than through a base socket.
The DE3425 has a length of 41mm, which is the critical physical constraint governing whether a festoon bulb fits a given housing.
End-cap contacts on the DE3425 require a holder that grips both ends of the bulb, a mounting style distinct from wedge-base or bayonet-base designs and therefore not interchangeable with those types.
The DE3425 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
Because the DE3425 specification remained unchanged across the entire 2004-2008 production run of the Suzuki Forenza, a single bulb type serves all listed model years without variation.
