Additional Notes

The Toyota Corona dome light uses one of two festoon bulb types across its 1969-1982 model years: DE3022 or DE3175, both of which are ANSI-standardized for the US and Canadian markets.
Festoon bulbs are cylindrical lamps that make electrical contact through metal caps at each end rather than through a base socket, which is the defining characteristic of the end-cap contact design shared by both bulb types in these specifications.
Both the DE3022 and DE3175 are 31mm in length and operate at 12 volts, placing them in the same physical and electrical class of festoon bulb.
The Toyota Corona (1973-1982) uses the DE3022 for its dome light, covering a span of ten model years with a single bulb specification.
The 1969-1972 model years use the DE3175 instead, representing a distinct fitment group from the later DE3022 application.
Although the DE3022 and DE3175 share the same 31mm length and 12V rating, they carry different part designations, which indicates they are not confirmed as interchangeable and should be treated as separate fitments according to the specifications.
