Thank you for viewing this item. Please read to the end. This is a yellow LED rotating light, a stand-alone type. It has several different flashing patterns. It's quite bright and noticeable. This product does not have a logo, but it is the same as the ALTEED product, so please research it if you are interested. I used this with 12V, so I don't know if it can be used with 24V. There are some minor scratches, so please check the photos and consider purchasing only if you are satisfied. There are no cracks, and there are no problems with use. Please note that I cannot offer discounts or specify shipping methods, including shipping costs, upon listing this item.
