You know your stuff! I am more of a lazy bugger and called Autofficina to book me in next weekend to change the bulbs along with some other minor work. When they send me over the quotation I will see what bulbs they are offering and suggest Osram Nightbreaker Lasers or Philips Xtreme Vision. Are these 'yellow light' or 'white light' output? I don't want to change the look to be too modern for this car as it is a beauty as it is.
