I thought id have a stab at changing my rear indicator clusters yesterday,which was not alot of fun,but well worth it. The problem I had was that my car has aftermarket parking sensors,so i couldnt fully remove the rear bumper. I ended up taking out all the fixings for it,and having it pretty much resting on a few areas so I could get to the screws for the clusters. Imagine my mood when I discovered that the bulbs were the wrong ones. I ended up replacing both clusters,but used the original bulbs,as i figured that i can change them when they arrive,and i didnt want to be removing the rear bumper again. Amazed at the difference its made to the back of the car though,much better,will look brilliant when the new bulbs rock up.
Sorry,no pics yet,but will post up when the new bulbs are fitted.
