This automotive maintenance tutorial was specifically written to assist owners of the first generation (2017, 2018, 2019 and perhaps also the 2020 and 2021 model years) Chrysler Pacifica minivan in changing a burnt out front side marker light bulb located in the front bumper cover near the wheel well liner and the front quarter panel.

Owners of other FCA (Fiat Chrysler America) vehicles from Chrysler, Dodge, Jeep, RAM or Fiat such as the Town & Country, 300, 200, Charger, Challenger, Durango, Journey, Grand Caravan, Wrangler, Grand Cherokee, Compass, Renegade, Patriot, RAM 1500, RAM ProMaster City, Fiat 500 and Fiat 124 may also find these DIY instructions to be helpful.

The compatible replacement miniature wedge base light bulb part number is 2821 (also known as W3W).

You could also use a brighter 2821 LED bulb.

The tools needed to access and replace the bulb include an 8mm socket with a 1/4" drive ratchet and a flathead screwdriver or a plastic pry bar tool.
