Honda Odyssey Fog Light Bulb Size

Additional Notes

• The front fog light specifications for the Honda Odyssey span model years 1995 through 2020, covering three distinct bulb types across that period: H3, H1, H8, and H11.
• The H11 bulb is the most frequently specified front fog light across this range, appearing in the 2008-2017 model years. It is a single-filament halogen bulb rated at 12V and 55W, using a PGJ19-2 base, and conforms to ECE standards with US approval.
• The H8 bulb appears in two separate periods: the 2005-2007 model years and again in the 2018-2020 model years. For the 2018-2020 Honda Odyssey, the H8 fitment applies specifically to vehicles equipped with halogen capsule headlamps. The H8 operates at 12V and 35W with a PGJ19-1 base.
• Although the H8 and H11 share a visually similar PGJ19-series base family, their base designations differ. The H8 uses a PGJ19-1 base while the H11 uses a PGJ19-2 base, and the two are not interchangeable despite their physical resemblance.
• The H8 also draws notably less power than the H11, at 35W versus 55W, which reflects a difference in intended output and socket design between the two bulb types.
• The H1 bulb is specified for the 2001 and 2004 model years. It is a single-filament halogen bulb rated at 12V and 55W, using a P14.5s base, and carries ECE approval as well as US and Japanese market approval.
• The H3 bulb is specified for the 1995-1997 model years. Like the H1, it is rated at 12V and 55W and holds ECE, US, and Japanese approval, but it uses a PK22s base, which is physically distinct from the P14.5s base of the H1.
• The H1 and H3 bulbs share the same voltage and wattage ratings but use different base types, meaning they are not interchangeable despite identical electrical characteristics.
• All four bulb types listed in the specifications are single-filament halogen bulbs operating on a 12V system, consistent with standard automotive fog light design across the covered model years.
• The trim-level conditional note attached to the 2018-2020 H8 fitment indicates that not all vehicles within those model years necessarily share the same fog light bulb, depending on headlamp configuration.
