12v Magnetic Tail Lights is what we use - they mount just abouot anywhere on your rack.. Got um from Harbor Freight and they work great - the magnets are super strong. Amazon has them also, but I liked the ones from Harbor Freight better. https://www.harborfreight.com/12v-magnetic-led-towing-light-kit-64282.html
Did you also move your license plate? For cross-country trips I feel more law-abiding to keep the plate 100% visible as required in 48 of 50 states — I use bike covers so I have a separate license plate bracket which requires reinstalling the license plate into the lighted holder. I like your light set-up. Will look into it. I have a KUAT carrier. I built a light bar that I Velcro onto the rear bike cover and/or wire ties to the bike spokes sans cover.

No, did not/have not moved license place. I feel that my tail lights are an important safety item, and as long as you drive safely with your stop lights & turn signals visible,, the popo are not going to be interested in your license plate - at least not in my area of the US.
