Jeep Liberty front and rear side marker bulbs utilize 168 and 3157 bulb sizes respectively. The replacement chart covers vehicle production spanning 2002 to 2012.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Jeep Liberty uses two distinct bulb types across its front and rear side marker positions: the 168 and the 3157, both of which conform to ANSI standards recognized in the United States and Canada.
The 168 bulb is a miniature wedge type with a T10 form factor, rated at 12 volts and 4.9 watts. Its single-filament, low-wattage design is typical of small marker and courtesy light applications.
The 3157 bulb is a dual-filament wedge type with a T25 form factor, rated at 12 volts with a wattage of 27W on the high filament and 7W on the low filament. The dual-filament construction allows it to serve both steady marker and brighter signaling functions within a single housing.
The front side marker position on the Jeep Liberty uses the 168 bulb across the 2002-2012 model years.
The rear side marker position on the Jeep Liberty uses the 3157 bulb for the 2008-2012 model years.
The T10 and T25 designations refer to the tubular bulb body width, with T10 indicating a narrower profile than the T25. These two types are physically incompatible with each other's sockets due to differing wedge base sizes.
The 3157's dual-filament design means its wedge base contains two separate contact points, which distinguishes it electrically and physically from single-filament wedge bulbs such as the 168. Substituting a single-filament bulb in a dual-filament socket would result in incomplete circuit function.
