Scalia Motorsports also has a nice line of rings .... and they have screens that you can use with their rings or the Merrick rings. https://scalia-motorsports.com/Headlight-Rings-for-All-2015-2020-Dodge-Challengers-c37213005 The WorkPlayDrive dude on YouTube has used both. Here's a link to one of his videos if you're interested.
I bought merricks rear mount headlight intake tube screens and caps (paid 155.15) and ended up throwing them in the trash, complete cheap a$$ junk and he won't answer any of my emails asking for a refund. Once installed there isn't anything left to grab onto (un-like the factory ones with the tabs or ears you can push against) and once they have been in there a while with all the road grime and dirt they will probably be next to impossible to get out. No groove for o-ring, just a bead of silicone, I guess to help make their installation even more permanent.
To each their own, i never was into trinkets if mopar thought there was going to be a problem they would have had a screen. if there is a go fast item that was not going to chop the car up or take away from the great looks of the SRT i am all in. why not hang a pair of dice around your rear view mirror ? again everyone has there own opinion and this is mine.
