    I've had both replaced and already one is showing yellowing. I'm about 9,000 miles away from warranty expiring so once I get close I'll request both to be replaced AND the UV fix on the center display. Only kicking the can down the street.

    I am just wondering for those who recently had their drl turn yellow if you know how old the lights are. I think the latest ones are revision F on the part number. Hoping that this new revision is better than the D I have. Both sides burned out partially with some yellow. Out of warranty.

    I've had both headlamps replaced on October 2019 with part number LH 1053570-00-D and RH 1053571-00-D. By April 2020 I had the RH side replaced with part number 1053571-00-F. At the time the tech mentioned that the driver side was more yellow than the passenger side (couldn't really tell at the time, the RH side was really yellow when I submitted the request). He mentioned I should put in a req to get it replaced. I haven't bothered side I know 1) it will just happen again and 2) may as well wait until my warranty is about to expire and replace it then in hopes of getting the most recent version. I haven't really looked as I haven't been driving much at night to really notice but I will try to take a look to see just how yellow both are.

    The D revisions seem to last for about a year for me. I also have one D (yellowing) and one F (newer, still good). I think it's too early to make judgment on the F revision since they haven't been in production long enough.

    Revision doesn't mean improvement, it could be a revision because they found a cheaper or more efficient way to make something, for example.

    Here are my headlights. The yellowed driver side was replaced in 2019 (revision D) while the passenger replaced in 2020 (revision F).
