Additional Notes

The Chevrolet Prizm uses the DE3175 bulb for the dome light across all listed model years, spanning 1998-2002.
The DE3175 is classified as a festoon-type bulb, meaning it is cylindrical in shape and makes electrical contact through metal caps at each end rather than through a base socket.
Festoon bulbs are held in place by spring-loaded clips that press against the end caps, a mounting method distinct from wedge or bayonet base designs.
The DE3175 has a nominal length of 31mm, which is the critical fitment factor for festoon bulbs, as the spring clips must compress correctly against the end caps to maintain a stable connection.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
The DE3175 designation follows ANSI standards recognized in both the United States and Canada, indicating the bulb conforms to a defined set of dimensional and electrical specifications within those markets.
Because festoon bulbs are sized primarily by length, substituting a festoon bulb of a different length, such as the 36mm DE3423, would result in an improper fit within the Prizm's dome light housing.
