2002 Hyundai Elantra replacing rear brake and running bulbs

Electrical problem
2002 Hyundai Elantra 4 cyl Two Wheel Drive Automatic

On other cars I have had it was simply a matter of going into trunk and removing trim behind rear lights and accessing bulbs. The elantra looks like its bollted
to the whole light housing. Am I missing something or do I need to unbolt the whole unit behind light to get to bulbs

Thanks
