The Jeep Compass fog light utilizes H11 and 9145 bulb sizes for the front lighting assemblies. Data for the specific components covers the period from 2007 through 2023.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
ANSI and ECE standard (US, Canada & worldwide). Single-filament halogen bulb with PG20-7 base. Recognized in both US and European regulations. 12V, 24W.
The Jeep Compass front fog light uses three distinct bulb types across its model years: the H11 for 2017-2023, the PSX24W for 2010-2013, and the 9145 for 2007-2009.
The H11 is a single-filament halogen bulb rated at 12V and 55W, fitted with a PGJ19-2 base. It follows ECE standards and carries approval for use in both European and North American markets.
The PSX24W is a single-filament halogen bulb rated at 12V and 24W, fitted with a PG20-7 base. It is recognized under both ANSI and ECE regulations, making it compatible with US, Canadian, and international standards.
The 9145 is a single-filament halogen bulb rated at 12V and 42W, fitted with a PY20d base. It follows ANSI standards applicable to the US and Canadian markets.
The H11, PSX24W, and 9145 all use different base types, meaning none of these three front fog light bulbs are interchangeable with one another despite all being single-filament halogen types.
The PSX24W operates at 24W, which is notably lower than the 42W of the 9145 and the 55W of the H11, reflecting a difference in power draw across the Jeep Compass front fog light generations.
The rear fog light on the Jeep Compass uses the 7440 bulb across all listed model years. The 7440 is a single-filament wedge bulb in the T20 form factor, rated at 12V and 21W, and follows ANSI standards for the US and Canadian markets.
The 7440 wedge base design differs fundamentally from the pin and bayonet bases used in the front fog light bulbs, making cross-position substitution physically incompatible.
At 21W, the 7440 rear fog light bulb draws considerably less power than any of the three front fog light bulb types used across the Jeep Compass lineup.
The front fog light bulb in the Jeep Compass (2017-2023) changed to the H11 from the PSX24W used in earlier generations, representing a shift in both base type and wattage for that position.
