Flickering leds in my 2013 X5

I recently replaced all of my interior lights with LED's from superbrightleds.com. They look great and make a huge difference in the inadequate factory lighting. The only SERIOUS problem is that all of them are flickering with the exception of the under dash, under rear seat, and cargo area lights. This condition only occurs when the engine is running. If you shut off the engine the flickering stops. Does anyone know of a remedy?

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.
