Ford Freestyle Forum : “how do i change tail light lamp on freestyle”

You will have to pull off some plastic panels on the interior of the vehicle to get to the tail lights.  Usually there are only a couple of fasteners holding on each light assembly.  If you are trying to replace bulbs then you can do it without having to remove the entire tail light.

Nope! Sorry.
There is one or two screws to un-screw once you open the tailgate. Once those two screws are out, you pull the lense unit straight out... it is kind of tough to get out... consider a screwdriver with a towel on the end to wedge it out... be VERY CAREFUL NOT to scratch your paint.

Once the lense unit is out, you unscrew (i think it is 1/2 turn) the bulb holder out.

Have a splendorful day!

Sean2349 is right on this one.  You have to remove the tailight assy to get to the bulbs.  I've attached a photo to help people understand the front tabs that Sean2349 mentions
