Our 2017 GT had halogens, we converted to Led's and a big improvement in vision and backup camera clarity.
Quoting myself for no reason other than to say I remember a time, pre March 2020, when my problems included light brightness and not Covid! Sort of sad to think back.I'm not sure a helicopter spotlight could improve that cam!!!
In all seriousness, I'm not sure why that cam is so poor and collects dirt so easily, but I'm beating a dead horse we've all beaten here already.
I have a 2019 Sig and if I have LEDs it isn't nearly enough. But I bet any improvement is welcomed for those without LEDs.
