Replacing d1s Bi-Zenon bulbs

[CowleyStJames]

I have a 2011 E250 with Bi-Zenon bulbs and one bulb is going pink as slow to start up.
Got two new bulbs coming tomorrow and just wanted some pointers to changing them out.
Anything to watch out for guys?

Turn them off first lol
Seriously though, they are high voltage so make sure they key is out etc. Once you have removed the round plastic cover, gently pull off the metal plug off the bulb (usually downwards), then the bulb twists about 45 degrees anti-clockwise, then pull it out carefully. Some have a round plastic collar to swap over from the old bulb to the new one, then re-assemble.
It’s always advisable to change both bulbs, as the colour changes with age.
I would buy quality replacements from a reputable source as there is a lot of fake Chinese tat on eBay/amazon etc.

Thanks cheddar, bought from Powerbulbs genuine Osram.
Never changed Bi-Zenon before and the dealer wanted crazy money to do the job
