Hi can anyone help resolve my quest to find out how i can upgrade my sidelight bulbs (E320cdi 54 plate) to the same style as the 07/08 plate W211 which match the xenons. I have tried the philips blue vision w5w which give a slight improvment and i have heard about the piaa type but without trying to go through all the different types i would like to find out how to get the same effect in one go. Any help would be appreciated...Thanks!
