C6 2013 Grandsport Headlights

I had a problem with my original headlights after 5 years. They were taking in water from rain and washes. I had them replaced with what I believed were equivalent headlights. After 4 years, they look worse than my original headlights (See pic). Now they appear to be cracking and are yellowing while in the garage during the pandemic. Any ideas who has the best deals in replacing my headlights?
