d1s

Hi guys, ive got an w211 e class - i have stock bulbs in the headlights and i wanted to upgrade them to D1S Xenon - is there a way on how i can do this- does there need to be anything done to prior or changes to the ECU- or i sit basically just a straigt swap thanks

Guys, Was looking to swap out the standard 4300K D1S bulbs that are fitted to my Intelligent Light system for 5000/6000K bulbs to get rid of that bit o yellow in the light. Had a look today and I cant see any retaining latches or locks? Do these bulbs twist to unlock from the headlamp...
