have you checked temps with and without the lights? Just wondering how much (if at all) the lights affect airflow thru the grill
Yeah, I haven’t noticed much difference with or without lights. If you look back a few posts you’ll see I’ve had 3 lights on the front bumper for a long time. I’ve removed the center light now to allow more air to directly hit the grill/radiator. Not much change.

As I mentioned earlier, in general my coolant temps aren’t that bad. But it just gets really hot in the engine bay and I think any reduction in those temps can only help so I’m trying a few things.
