my 1985 500sel's trunk light has never worked since i got it in 94 and i havnt gotten around to changing it latley ive been trying to figure out where it is i can't find where. i can find where the main wiere is when it first starts in to the trunk but i cant find the buld. where can i get a buld and where is it. one last thing in the center of my trunk there is a peace of duck tape if seen that on a few mercedes what is it for right in the middle
