The Jeep Wrangler fog light utilizes H3, 9145, and PSX24W bulb sizes depending on the specific application for the front lighting assembly. Data for the bulb sizes covers the range from 1995 through 2024.
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 PSX24W is the most widely specified front fog light bulb across the Jeep Wrangler lineup, covering model years 2010-2016 without condition and 2024 without condition, as well as 2017-2020 on trims equipped with halogen capsule headlamps.
The PSX24W operates at 12V and 24W, uses a PG20-7 base, and carries both ANSI and ECE certification, making it recognized under US, Canadian, and international lighting regulations.
On the Jeep Wrangler, the 2017-2020 PSX24W fitment is conditional, applying only to vehicles equipped with halogen capsule headlamps, which indicates that other headlamp configurations on those model years may use a different fog light arrangement.
The H3 bulb is specified for front fog lights on model years 1994-2006, with the 1995 entry noting an additional H3 position located in the grille under the Sahara Package.
The H3 operates at 12V and 55W with a PK22s base and follows ECE standards, though it also holds approval in the US and Japan, placing it among the higher-wattage options in the Wrangler fog light specifications.
The 9145 bulb is specified for the 2007-2009 front fog lights, operating at 12V and 42W with a PY20d base under ANSI standards, positioning it between the H3 and PSX24W in terms of wattage output.
The 9145 and H3 are not interchangeable despite similar voltage ratings, as they use different base types, PY20d and PK22s respectively, which are physically incompatible with each other's housings.
The rear fog light on the Jeep Wrangler uses the 168 bulb for the 2014-2015 model years, a miniature wedge-style T10 bulb rated at 12V and 4.9W under ANSI standards.
The 168 rear fog light bulb operates at a substantially lower wattage than any of the front fog light bulbs in the specifications, reflecting the functional difference between a low-intensity rear visibility lamp and a forward-projecting fog light.
Across the full span of front fog light specifications, three distinct base types are present: PG20-7 for the PSX24W, PY20d for the 9145, and PK22s for the H3, none of which are cross-compatible.
