rear license plate light

i got a 2001 sc2. how do you remove that black plastic rear license plate light? i'm trying to remove the plastic lenses to remove a burned out bulb
& i stripped the screws. they must screw into metal & are rusted or something, so i guess i'm just going to have to just replace the lamp assembly...

assuming your is like my 94...

did you use the proper T15 bit driver?
