The Chrysler Town & Country fog light utilizes 9145, 9040, and H3 bulb sizes according to the provided technical specifications for the lighting components. Available data covers the period from 1996 through 2008 for the specified vehicle lighting equipment.
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 Chrysler Town & Country front fog light uses three distinct bulb types across its model history: H3 (1991-1997), 9040 (1998-2004), 9145 (2008-2009), and PSX24W (2010-2016).
The PSX24W is a single-filament halogen bulb rated at 12V and 24W, built to both ANSI and ECE standards, making it recognized in the US, Canada, and international markets. It uses a PG20-7 base.
The 9040 and 9145 bulbs share the same PY20d base and both operate on a 12V single-filament halogen design, though they differ in wattage: the 9040 draws 40W while the 9145 draws 42W. Despite this similarity, they are not the same bulb type and are not listed as interchangeable in these specifications.
The H3 is an ECE-standard single-filament halogen bulb with a PK22s base, rated at 12V and 55W. It carries approval in the US and Japan in addition to European markets.
At 55W, the H3 operates at a significantly higher wattage than any other front fog light bulb listed for the Town & Country, including the PSX24W at 24W and the 9040 at 40W.
The rear fog light position on the Chrysler Town & Country (2015-2016) uses the 3757NA, a dual-filament wedge bulb in the T25 form factor with natural amber glass, rated at 12V and governed by ANSI standards for the US and Canadian markets.
The 3757NA is the only dual-filament bulb across all fog light positions listed in these specifications. All front fog light bulbs are single-filament designs.
The PSX24W is the only front fog light bulb in these specifications that carries dual regulatory recognition under both ANSI and ECE standards, distinguishing it from the H3, which is ECE-primary with US approval, and the 9040 and 9145, which are ANSI-only.
Base type compatibility is a relevant fitment consideration across these bulbs. The PG20-7 (PSX24W), PY20d (9040, 9145), PK22s (H3), and wedge T25 (3757NA) are all physically distinct and non-interchangeable with one another.
The 9040 and 9145 share the PY20d base, which is a physical commonality, but their differing wattage ratings and separate ANSI designations indicate they are specified as distinct bulbs for their respective model years.
