Additional Notes

The 194 bulb is the high beam indicator bulb size for the Ford Explorer across the 1991-2000 model years, making it the dominant fitment across this generation.
The T10 miniature wedge is the bulb form factor used throughout all listed model years of the Ford Explorer high beam indicator position, operating at 12V and 3.78W.
Both the 194 and PC194 share identical electrical ratings of 12V and 3.78W, and both conform to the ANSI standard applicable in the United States and Canada.
The PC194 differs from the standard 194 in its socket type. Where the 194 uses a standard wedge base, the PC194 incorporates a printed circuit board twist-lock socket, which is specific to instrument cluster applications.
The 2001 Ford Explorer high beam indicator position calls for the PC194 rather than the 194, reflecting a socket configuration change from the prior model year.
The twist-lock socket of the PC194 is not physically interchangeable with the standard wedge socket of the 194, meaning substitution between the two types is not straightforward despite their shared electrical characteristics.
