Hello together, I am enjoying buying my V70 new Xenon burner. D2R bulbs are original installed. Can you give me a few tips regarding the new bulbs. I have considered the Philips D2R Vision or Ultra Vision. Can you recommend them to me? Do you have product numbers of the listed burners? Where best to order? Or do you have a completely different company that can be bought? Regarding the change of lamps. Can you do this yourself? Is there any guidance on the various steps of installation? Thank you for your help. Greeting Sebastian
