How do you change tail light subaru tribeca?

When you open the tail gate there are two tabs in the tail gate channel to the left of the tail light assembly. Prize these tabs out with a small flat blade screwdriver to get access to the Phillips Head screws underneath. Remove these screws and slide the tail light assembly towards the rear. This will give you access to the stop/tail light bulb. Replace the faulty bulb with the correct double filament 12 volt 21/5 watt bulb. Reassemble by reversing the steps above and click the tabs back into place. While you have the tools out, it is a good idea to replace the bulbs on both sides of the car as the other bulb has had identical use and may not last much longer anyway.
