We're also preparing to undergo this, however when searching the parts catalog I'm only seeing two numbers being displayed (obviously per left and right.)
Now, I've seen three separate
bi-xenon assemblies within the community: black, a muted chrome, and also a dark grey colour.
My query is whether anyone is aware of what
bi-xenon assemblies correspond to what vehicles, e.g. pre-facelift, M sports, EU, US, particular years &c.
Any insight would be helpful.
