Additional Notes

The DE3175 is the dominant dome light bulb type across the Toyota Celica's production history covered by these specifications, appearing in model years 1971-1974, 1987-1993, and 2000-2002.
Both the DE3175 and DE3022 are ANSI-standardized festoon bulbs rated at 12 volts, with a 31mm length and end-cap contacts, meaning they share the same physical form factor and voltage rating.
Despite their identical physical and electrical characteristics, the DE3175 and DE3022 are listed as distinct part numbers, and the specifications treat them as separate fitments depending on the model year.
The Toyota Celica (1975-1981) is specified with the DE3022 rather than the DE3175, representing the only production period in these specifications where the DE3022 is the designated dome light bulb.
Festoon bulbs make contact with the socket through metal caps at each end of the cylindrical housing rather than through a base pin or wedge, which is a defining characteristic of this bulb family.
The 31mm length is a critical fitment factor for festoon bulbs, as the socket holds the bulb under spring tension between two contact points spaced to match that length.
