Additional Notes

The Suzuki Equator uses the DE3425 bulb for the map light across all documented model years, spanning 2009-2012.
The DE3425 is an ANSI-standardized bulb type, meaning it conforms to a defined specification recognized across the United States and Canada.
The DE3425 is a festoon-style bulb, which is a cylindrical form factor held in place by spring-loaded clips at each end rather than a socket.
Electrical contact on the DE3425 is made through end-cap contacts, the metal caps at both ends of the bulb body.
The DE3425 has a physical length of 41mm, which is the critical fitment factor for festoon bulbs, as the spring clips must compress correctly to hold the bulb securely.
The DE3425 operates at 12 volts, consistent with standard automotive electrical systems.
Because festoon bulbs are sized by length, substituting a bulb of a different length, even one that is otherwise electrically compatible, may result in a poor or failed fitment in the Suzuki Equator map light housing.
