I just traded my pickup for a 99 clk430 (which my husband thought was a crazy idea, but I loved the car). The side marker/turn signal light cover on the front fender was missing, so instead of replacing it with a clear one I purchased a set of smoke colored ones with the chrome bulbs. It doesn't come with instructions except telling me to take it to my closest dealer or garage. Can someone step me through changing them out myself? I need to pop off one, change the bulbs on both and then put new covers on. Any help would be gladly appreciated.
