That word "good" there is carrying a lot of weight. There's a line of Chinese-made headlite-shaped things, sold by Holley, that look more or less like old-fashioned headlamps. They're fine if you don't drive at night (in which case, so are cruddy sealed beams). The sad part is, it would not have cost more to do it right.
Now if only somebody would develop such a product with actual, appropriately knowledgeable engineering as one of the ingredients…!
