Not sure what the little bulbous protrusion is supposed to be, but here's a pic of the cortina's tail lights...

I've attached a ref pic showing the chrome piece over the tail lights. I'd model the lights seperately from the chrome piece. The lights look like they're supposed to be completely flat... then the mercedes-style chrome piece over that. The center... protrusion... is only part of that chrome trim, and should be modeled as part of that piece, not the tail light...
