Additional Notes

The Ford Explorer front fog light specifications cover model years 1993 through 2018, with three distinct bulb types appearing across that span: the 9145, H11, H1, H3, and 899.
The 9145 is the most frequently specified bulb across the Ford Explorer fog light data, covering model years 2002-2010 and 2016-2018. It operates at 12V and 42W, uses a PY20d base, and follows the ANSI standard applicable in the US and Canada.
The H11 bulb is specified for the 2011-2015 model years. It operates at 12V and 55W, uses a PGJ19-2 base, and follows the ECE standard with additional approval in the US.
The 9145 and H11 are not interchangeable. Despite both being single-filament halogen bulbs rated at 12V, they differ in wattage and base type, with the 9145 using a PY20d base and the H11 using a PGJ19-2 base.
The H1 bulb is specified for the 1999-2001 model years. It operates at 12V and 55W, uses a P14.5s base, and carries ECE, US, and Japanese approvals.
The H3 bulb appears in the specifications for 1993-1998 model years. It operates at 12V and 55W, uses a PK22s base, and is approved under ECE standards as well as in the US and Japan.
The 1995-1998 Ford Explorer carries a dual fitment, listing both the H3 and the 899 bulb for the front fog light position, indicating that two separate fog light assemblies or configurations existed in those model years.
The 899 bulb operates at 12V and 37.5W, uses a PGJ13 base, and follows the ANSI standard. At 37.5W, it produces less power than the H3 listed alongside it for the same years.
The H1, H3, and H11 bulbs all share a 12V, 55W rating but use entirely different base types, making them physically incompatible with one another despite identical electrical ratings.
A base type mismatch is the primary fitment concern across the Explorer fog light history, as the five bulb types specified use five distinct bases: PY20d, PGJ19-2, P14.5s, PK22s, and PGJ13.
