DIY Damaged 2015 LX570 headlamp assembly replacement? (6 Viewers)

[JMC5000]

Hello, the passenger side headlamp on my 2015 LX570 suffered some parking lot damage and nearly the entire plastic/polycarbonate lense cover was broken out. The bulbs are intact and I don't believe that any other damage occurred to the assembly. I've searched the forum and wasn't able to find any insight into DIY repairs. I have been able to find replacement assemblies on line and would be willing to use a non OEM replacement if possible. My question is how difficult swaping it out will be? Thanks for any help the forum can provide.
