I have these Diode Dynamics lights installed.
https://www.4x4truckleds.com/diode-dynamics-stage-series-ss3-ditch-light-kit-for-2021-ford-bronco/
I optioned them with amber backlights & the combo pattern at the sport power level.
$240 (you don't need the KR brackets - they come with the bracket that is pictured)
Install is very, very simple to an aux switch.
Has a plug/play harness included.
I can't remember how they recommend the backlight be wired, because I just spliced that line into something else that was already on a fuse tap (the light up BRONCO letters)
I've been very happy with that site - I broke a bolt installing these & he mailed me a free hardware kit the next day.
Great customer service.
Edit - just saw the OP said they prefer round lights.
Diode does offer SS3 lights in round, the same site has them - I'm not sure if you can purchase the wire harness from 4x4truckleds separate from this kit or not, but if you can, it would probably install the same.
I ordered "generic" non Bronco specific SS3 square lights like this for fog lights & reverse lights & they mount the same & have the same connections, so I imagine the round SS3 lights would as well.
