I first found the listing for French model amber lamps in the MBZ parts microfische catalog 25 years ago and tried to order them, they were not available through the USA parts network, but I always thought it would be cool to have amber fog lamps. That section is still in the parts listings but the number subs to same number as the clear bulbs.
I tried an experiment with a transluscent stained glass paint that is available in hobby craft stores and painted my bulbs amber.
I mixed up some of this paint to a yellow-orange (amber) color and dipped the bulbs in the paint, it took several coats to get the same depth of color as an 1157na turn signal bulb.
I allowed the paint to cure for several days before installing them, they sent off some smoke for about the first 5 minutes.
I ended up coloring the marker lamp peanut bulbs too because they light up a white spot in the corner of the lense.
