Although I have had this product for quite a while, I just installed it two months ago and I have to say that it is amazing for the price. It would just be better to go to a professional to install it so that it connects in such a way that it turns on with the car's lights. Your pair of lights can transform any car; now I don't know about the lifespan of this product, but it looks good and seems to hold up quite impressively. For your information, in most electrical shops, the price is around 20 €
