Additional Notes

The Daihatsu Charade uses the DE3175 bulb for the dome light across the 1988-1992 model years.
The DE3175 is an ANSI-standardized bulb type, meaning it conforms to a defined specification recognized across the United States and Canada.
The DE3175 is a festoon-style bulb, which is a cylindrical lamp that seats between two spring-loaded contacts at each end rather than fitting into a socket base.
The 31mm length of the DE3175 refers to the distance between its two end-cap contacts, which determines physical fitment within the dome light housing.
The DE3175 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
Because the DE3175 designation is an ANSI standard, bulbs carrying this designation from different manufacturers are generally interchangeable as long as the 31mm festoon form factor and 12V rating are maintained.
