Got some of these in the mail and I stuck one in my 89 diplomat and it works so that’s a good start I did have to flip it over because of polarity. It’s a green one looks pretty bright just need to get the dash back together and see how it looks then and maybe will need to be dimmed to about 3/4. https://www.superbrightleds.com/mor...25-miniature-wedge-base-135-lumens/6325/
