Toyota Celica Instrument Panel Bulb Size

Additional Notes

• The Toyota Celica instrument panel uses two bulb sizes across its model years: the 194 and the 74, both of which are ANSI-standard miniature wedge bulbs rated for 12 volts.
• The 194 bulb follows the T10 wedge form factor and draws 3.78 watts, making it the higher-wattage of the two types specified for this application.
• The 74 bulb follows the T5 wedge form factor and draws 1.4 watts, a notably lower output than the 194.
• Although both bulbs share the same wedge-base design, the T10 and T5 form factors are not interchangeable due to their differing physical sizes, and substituting one for the other in the Toyota Celica instrument panel would result in an improper fit.
• The 194 bulb is specified for the Toyota Celica across the majority of model years in the data, including 1971-1981, 1987, and 1989-1999.
• The 74 bulb is specified for the 1982-1986 model years, with the exception of 1987, which returns to the 194 specification, and 1988, which uses the 74 again.
• The 1987 and 1988 model years each carry a different bulb size from the other, indicating that instrument panel bulb fitment is not uniform across adjacent model years in that period.
• Both the 194 and 74 bulbs carry ANSI standardization applicable to the United States and Canada markets.
