The replacement L.E.D. work well. The improvement over the stock incandescents is remarkable. To be fair, I don't how these compare to other products of similar design. But having used these for a few weeks, I wouldn't want to go back. The one problem I had was the really inadequate installation instructions. Fortunately, several emails and internet searches help me figure it out. There is no reason for it to be unclear or incomplete instructions. Just seems to be too common today. So, good product, terrible instructions. If I hadn't had to go through so much, I would have given this product 5 stars.
