I thought these were perfect, at first. A nice, deep red, and not too bright or too dim for my rear parking lights. Then, earlier today, less than 5 weeks after purchase, one of them became so dim that it was effectively burned out. I swapped them to make sure it was the LED that wasn't working, and sure enough, it was. I am very disappointed. I thought this was a good brand, but I should have read the reviews first. Many people have had the same problem. Sylvania or Philips is the way to go.See full review
