Replace clear lexan headlight cover advise...

[LennyBoy1]

I think my BMW 2008 X5 has the Zenon Bi-Directional Headlights (they move slightly when I start the car). Next spring, I want to replace the passenger side headlight cover - just the clear Lexan cover but not the complete headlight assembly. The headlights are still plenty bright enough...but the passenger side headlight has lots of surface scratches & lots of internal hairline cracks. A polish kit obviously won’t remove the cracks. The headlights are over $1800 each at RockAuto - yikes!. The clear replacement covers are about $40 each on Amazon. I watched some YouTube videos and it looks like it’s not that difficult but requires that you remove headlight and heat up the headlight slightly with heat gun & cut the clear headlight cover off the rest of the assembly. Then clean up the surface and re-glue the new cover on.

Has anyone done this task on the X5 and any advice? I searched the forums but couldn’t find much. Thanks for your assistance.
