This is a reproduction KD-540 marker light base. It is made out of 3/16 aluminum so it will not rust like the original steel ones. Comes with the pigtail. We recommend using a #63 or 67 bulb. The photo with lens is a reference only. These are custom made and may have a delay of 2-3 weeks in being delivered when ordered if not already made. Made in the USA.
