南非采购需求：红绿灯

I'm looking for solar-powered traffic lights designed for highway use. It's essential that these lights are durable and weather-resistant, as well as energy-efficient to maximize sunlight utilization. Could you provide details on the available options, including specifications and pricing? I'm particularly interested in models that incorporate smart features for enhanced visibility and functionality, as well as any certifications they may have. Waiting for your quick response!
