Chrysler Pacifica Headlight Bulb Guide
What headlight bulb does a Chrysler Pacifica use? Here is the exterior bulb chart from the 2026 Chrysler Pacifica owner's manual, the manual's steps for the front turn signal and side marker bulbs, and how the headlight switch, automatic headlights and automatic high beams work.

The short answer
The 2026 Chrysler Pacifica owner's manual lists no headlamp bulb number. Its bulb chart lists three replaceable exterior bulbs: the front turn signal lamp (WY21W / 7440NA) and the front and rear side marker lamps (W3W / 2821). The manual says the vehicle is equipped with LED lamps and to see an authorized dealer for replacement of LED lamps, so if a headlight is out, have it checked by a dealer service department.

How the Pacifica headlight switch works
The headlight switch is on the left side of the instrument panel and controls the headlights, parking lights, instrument panel lights, interior lights and fog lights. From the O (off) position, rotate it clockwise to the first detent for the parking lights and instrument panel lights, and to the second detent for the headlights.
Automatic headlights (if equipped) turn the headlights on or off based on ambient light levels. Turn the switch to the extreme clockwise position, AUTO, to turn the system on; the engine must be running before the headlights come on in automatic mode. When the system is on, the headlights stay on for up to 90 seconds after the ignition is placed in OFF.
Headlight Time Delay (if equipped) can keep the headlights on for 30, 60 or 90 seconds, or not at all, after you exit; change the timer in Uconnect. The headlights must be turned off within 45 seconds of placing the ignition in OFF to activate it. To turn on the front fog lights (if equipped), turn on the parking lights or low beam headlights and push the headlight switch control knob; push it again to turn them off.

High beams, automatic high beams and turn signals
Push the multifunction lever toward the instrument panel to switch to high beams; pull it back to turn the low beams on. Lightly pulling the lever toward you flashes the high beams until you release it.
Automatic High Beam (if equipped) uses a camera mounted on the windshield to switch from high beams to low beams until an approaching vehicle is out of view. To activate it, select Auto Dim High Beams in Uconnect, rotate the headlight switch clockwise to AUTO, and push the multifunction lever away from you for the high beams. It will not activate until the vehicle is at or above 16 mph (25 km/h), and once active it stops functioning below 12 mph (20 km/h). Dirt, film and other obstructions on the windshield or camera lens will cause it to function improperly.
If a turn signal light stays on and does not flash, or flashes very fast, the manual says to check for a defective outside light bulb. If the turn signals stay on for about 1 mile (1.6 km), a chime sounds and a message appears in the cluster. If the headlights are left on with the ignition OFF, the exterior lights turn off automatically after eight minutes to protect the battery.

Cleaning the headlight lenses
The Pacifica has plastic headlights and fog lights. The manual's Cleaning Headlights section says plastic is not as scratch resistant as glass, so avoid wiping the lenses with a dry cloth, remove road dirt with a mild soap solution followed by rinsing, and do not use abrasive cleaning components, solvents, steel wool or other aggressive material to clean them.
