Very seriously for such a low price, I find small wonders have these lights! Indeed, for my part I put them on my car, and I have had no problems! Obviously I made the mistake of trying them, though it was pouring rain and I went up to 120 Km / h of 1-hour drive, a light and dropped me due to take water. In rainy weather I do not recommend their use, although possible evidence, but avoid nonetheless. At night, when it's not raining, it's really great to rave or get noticed a little. Very good product, cheap and still robust!
