Where is the fuse box for the rear lights on slk 230?

the fuse box is located under the hood on the driver side next to the firewall; it is about 4inch by 8inch, black in color, just lift up the lid and all the fuses are in there. You will probably have to refer to the fuse section in your owners manually or else just pull them out one at a time and you can tell if they are shot.
