Additional Notes

The DE3175 is the sole dome light bulb size listed across all model years of the Isuzu Amigo covered in these specifications.
The DE3175 is 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 within the fixture, which grip the end caps to secure the bulb and complete the circuit simultaneously.
The DE3175 has a nominal length of 31mm, which is the critical fitment factor for festoon bulbs, as the fixture's clip spacing must match the bulb length.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger and light utility vehicles.
The DE3175 conforms to ANSI standards, meaning its physical and electrical characteristics are standardized for the United States and Canadian markets.
The Isuzu Amigo uses the DE3175 across the 1989-1994 and 1998-2000 model years according to these specifications.
Because the DE3175 is an ANSI-standardized part, bulbs from different manufacturers carrying the same designation are generally interchangeable, provided the 31mm length and end-cap contact design are maintained.
