I have had good luck using an orange or yellow Sharpie. I have also used orange Tempera paint (like we used in Vacation Bible School art projects)Thanks for the response. I want to tone down (from bright) the exterior lights on the Mendards Melrose Park Station. I recall a discussion of toning down to a softer incandescent tone light by applying a specific brand/color model paint color to the LED bright white lights
Appreciate help
