Honda Ridgeline Fog Light Bulb Size

Additional Notes

• The Honda Ridgeline front fog light specifications cover model years 2006 through 2020, with two distinct bulb types used across that span.
• The H11 bulb is the more widely used of the two types in these specifications, appearing across nine model years from 2006 to 2014.
• The H11 is a single-filament halogen bulb operating at 12V and 55W, built to the ECE standard with a PGJ19-2 base, and carries approval for use in the United States.
• The Honda Ridgeline (2017-2020) front fog light requires an H8 bulb rather than the H11 found in earlier model years, making the two types non-interchangeable despite their similar appearance.
• The H8 is a single-filament halogen bulb operating at 12V and 35W, built to the ECE standard with a PGJ19-1 base, and also carries approval for use in the United States.
• The wattage difference between the two bulb types is notable: the H11 draws 55W while the H8 draws 35W, meaning the two are not electrically equivalent.
• Both the H8 and H11 use PGJ19-series bases, but the specific base variants differ. The H8 uses a PGJ19-1 base and the H11 uses a PGJ19-2 base, which prevents physical cross-fitment between the two types.
• Both bulb types share the same 12V operating voltage, consistent with standard automotive electrical systems.
• Both the H8 and H11 are single-filament designs, meaning each bulb serves only one lighting function rather than combining multiple functions within a single unit.
• The ECE designation on both bulb types indicates compliance with the United Nations Economic Commission for Europe lighting regulations, a widely adopted international standard.
