Both of my headlights are so fogged you can hardly see the road any longer! I have tried two different headlight cleaner products and they don't make any impact. I am looking at aftermarket replacements and have found two different oem part numbers. Does anyone know if there is any difference between these oem numbers?

Drivers 4857851AA vs 4857850AE
Passenger 4857850AA vs 4857851AE

Thanks,
Joe

 

It seems odd that each side has a 50 and 51, it would seem that one side would be 50 and the other side 51, but that's what the website(s) had listed. Basically I'm curious between the AA and the AE versions.
