I found a lot of posts in the archives about the Lux lighting kit for making the X1's daytime running light halo rings whiter and brighter than the stock dirty yellow color. Did BMW change the halo ring bulbs on the X1 during the last Life Cycle Impulse (product refresh), making these kits unnecessary for the newest X1s? The old threads reference an H8 halogen bulb, but I notice the 2013 X1 marketing information talks about LED DRLs. So are 2013+ halos already brighter/whiter than the earlier cars? Or do they still use the yellowish H8 bulb?
