I'm interested in sourcing 500mm foldable safety cones equipped with a light feature. Ideally, these cones should be lightweight, durable, and easy to set up, making them suitable for various applications, including road safety, construction zones, and event management. Please provide details on the materials used, weight specifications, and color options available. Additionally, it would be great to know the lead time for production and order quantities to qualify for bulk pricing. If you have any certifications or compliance standards that these products meet, please include that information as well. I'm looking forward to your prompt reply with the requested details and any available product images or catalogs!
