Have you tried reversing the polarity, ie turn the bulbs around in the socket? I know of a few people who have purchased from superbright, and have had issues, and others who have had none. When I put LEDs in the interior of my Grand Prix I had they would give me issues at first. I started messing around with each bulb one at a time and I finally got them to work as they should. Mine were purchased from an Amazon retailer, not superbright. I did have one fail for the license plate light in my Lancer, ie it had one chipset flickering and another was completely out.
