Help!! 06 Civic Ex sedan tailight removal

I get all four screws off, but then there is something else holding them on, and i cant seem to find it, and i am not knowledged enough to take off bumper

any advice????

Try this

Theres 1 screw under the lgiht located behind the rear bumper remove bumper (10 min job) then lights will pop right out
If you have rear mudflaps these should be removed first before the bumper is
removed. Then there is a screws on the bottom side of each taillight.
