E39 M5 Post Facelift Headlight Rebuild

Hi all,
Decided it's time to tackle the headlight issues on my e39, so I'm reaching out to fellow members before I begin this task. Recently my headlights have s*** the bed, with one side half working and the other side half working as well (both sides polar opposites). So, I figured I would either replace them, or rebuild the original units. This will be my first time tearing apart some headlights, so any advice is highly appreciated.

Essentially I am looking to swap the lens (originally US Post Facelift) with a clear corner alternative as one side of my current setup is yellowing quite bad. I am intending on upgrading the halos as well as all the obvious bulbs.

If anyone can recommend parts/advice regarding this sort of work, that would be greatly appreciated. Been having a hard time finding aftermarket replacement headlights that will fit a post facelift M5 with minimal wiring/modification, so it seems as though this is the better route. I would get some Euro Hellas but my bank account would be far from happy.

Thanks!

I thought you can't buy an OE lens for the post facelift headlight. You also may not be able to remove the lens due to an epoxy change. You need to check, but the change may have occurred in '02. You can wet polish and buff out yellowing lenses though. Usually the lights are long lasting and don't need rebuilding. I have only had to replace a Xe bulb on 1 car and the adjusters on all. The electricals have been fine.

I haven't found a cheap way to upgrade post facelift Xenon headlights. Actually I'm likely jumping the other direction and going all in on BiXenon upgraded lights .. $$$$$

I just did this a few weeks back. I bought replacement lenses through ecstuning for about $160 and they have the silver euro markers already attached.

As for separating the lenses, there are a few good YouTube videos on how to do it even if you have the epoxy. Basically you Dremel off most of the lens, leave about 1"along the seams and then use a utility knife to cut the epoxy on each side of the remaining piece. Then you can pull it off. Not a bad job but it takes time and patience.

You can get butyl based headlight sealer on Amazon and it works nicely for putting the new lenses on. Fits right in the seam and you just press the lenses in after applying some heat to the butyl.

you have any pics of your end result? I was considering this as well, but likely will have a friend just polish the lenses for now as that should last me awhile.
