Are the 07+ LCI xenon headlights completely interchangeable with the pre-LCI xenon headlights? Can I carry over the xenon related stuff like bulb, ballast and ignitor?

thanks in advance!

 

If you have the later model with D1S bulbs then yes. Not too sure about the adaptive module.

 

hi

thanks - what is the "adaptive" module? is that the motor that makes it go up and down? that's contained inside, right? My car is a 2004, so probably I don't have the D1S bulbs...

 

I believe you must have Xenon pre-LCI fixtures in order to get the LCI version and use them without errors. I also believe, don't quote me, that you need an adapter, (similar to Bruce cables), like you do in the rear for the LCI tails.

 

Ok, thanks

I'll just stick with getting some identical then.
