Thank you for viewing the product. Please read to the end. This is an ALTEED LED rotating light, yellow type. If you want to know the detailed specifications of the product, please look it up. Please refer to that information. There are several flashing patterns, and it is quite bright. I used it with 12V. I haven't tested it with 24V, so I don't know. Since it is used, please check the photos and consider purchasing only if you are satisfied. Due to the listing, I cannot offer price reductions or specify shipping methods with included shipping costs.
