Additional Notes

The Hyundai Excel uses the DE3175 bulb for the map light across all listed model years, spanning 1987-1994.
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 or pins.
The DE3175 carries an ANSI designation, indicating it meets a standardized specification recognized across the United States and Canada.
The bulb has a 31mm length, which is the critical fitment factor for festoon bulbs, as the end-cap contacts must bridge the holder's contact points at a fixed span.
The DE3175 operates at 12 volts, consistent with standard automotive electrical systems.
Because festoon bulbs are sized by their physical length, substituting a bulb of a different length, such as a 28mm or 36mm festoon, would result in an improper fit even if the voltage rating matches.
