I'm aware of some of the different angel eye's options and the LED bulbs, but I just wanted to know simply what would be a simple angel eye bulb replacement? I was looking to go with the same type of bulb just in a slightly more blue hue to match the xenons. I just can't seem to find what type of bulb it uses? I swapped out the stock ones in my 08' E92 coupe with the GP Thunder 8500k's and love the way they look. Not looking for brighter, just whiter. Thanks
