Toyota Camry Instrument Panel Bulb Size

Additional Notes

• The Toyota Camry instrument panel specifications span the 1983-2001 model years, with two bulb types appearing across that range: the 194 and the 74.
• The 194 bulb is the more frequently specified of the two, appearing in the majority of model years within this range.
• Both the 194 and the 74 are ANSI-standardized miniature wedge bulbs rated at 12 volts, making them compatible with standard automotive electrical systems.
• The 194 follows the T10 wedge form factor and draws 3.78 watts, while the 74 follows the smaller T5 wedge form factor and draws only 1.4 watts.
• Because the T10 and T5 wedge bases differ in physical size, the 194 and 74 are not interchangeable with each other, even though both use a wedge-style base.
• The Toyota Camry (1999-2000) specifies the 74 bulb, whereas the immediately adjacent years of 1997-1998 and 2001 call for the 194, indicating that the correct year must be confirmed before sourcing a replacement.
• The lower wattage of the 74 (1.4W versus 3.78W) means it produces less heat and draws less current than the 194, which is a relevant consideration when evaluating socket condition during replacement.
