This listing is for a lot of 3 Do-Ray Cab Amber Lens Lights. They measure about 15 1/2" long and have a diameter 3 1/2" across the lens. These were working when removed and will accept either a 6 or 12 volt bulb.
Please see the close up photo of one bulb which has a chip missing on the underside. I don't think this would be visible once installed. Price on these hard to find lights is reduced because of this.
Please feel free to contact me with any questions or if you'd like more photos.
