I got an ad on Facebook for Smart Bike Lights. Their headlight is called Farina. Commercial ads for gadgets on Facebook tend to be from small companies in China. That doesn't mean a product is necessarily bad, but I haven't heard of this company. The products look good, but what do I know. Does anyone know anything about the company or its products?

The thing that caught my eye is the StVZO design. The company claims it makes the Farina according to the requirement but does not claim it's certified. That's OK with me. I bought cheap Chinese lights that make the same claim, and they worked out very well for me. That light cost between $9 and $16, and I bought eight of them. They are out of production now, and I may want to buy a better-made light that's likely to last.
