Always wear nitrile gloves when handling bulbs as oils from your skin can damage the bulb and cause it to burn out prematurely. Once you have your replacement bulbs, your nitrile gloves and safety glasses on: open the trunk or the tailgate, move the fabric (or remove panel) and take a look behind the tail light lens. In some cases, you might have to remove the outside assembly. If removing the assembly is necessary, remove the fasteners (screws or bolts) and put them somewhere safe so you don’t lose them.
Do It Right:Most pickups will require removing the outside assembly.
