sorry to bother you agian but had to ask this one last question.
before i completly give up in the light mod and go with the drl.
the pic below shows a newer 5 series light and the back piece of plastic is removable (not the lense) does this hold true to the z3 series as well if so i believe this would give complete access to the bulb hole.
i looked at mine still installed and they have the tabs as in pic but not sure if its made to remove and install or just part of the assembly process
