How do you replace the license plate bulb on a 1999 Mercedes E320?

If you just need to replace the bulb(s), open the trunk lid and remove part of the felt liner. There are platic pins that can be easily taken out to do this. The bulb(s) can be accessed from behind the trunk lid. They are very inexpensive under $2); so you may want to change them both. The bulbs are bayonnet style and look like fuses; easily unclipped and replaced.

oddly, you can NOT do change the bulb(s) by loosening the 3 screws above the license plate that appear to hold the bulbs' lenses in place. It must be done from inside the trunk as described above.
