I made my own so I do not have any experience with these, but a major player has finally stepped up and is selling a retro fit 4 headlight style LED "sealed beam"! I don't know how long these have been available but I just noticed them in Hagertys rag. Price is $160 each. Also, you can get them Warm (Yellow) and Cool (White) color.
Currently have Morimoto LED fogs in one of my vehicles and they are a quality piece. This is another player in the game and what I've bought from them is outstanding. 2020-2022 Jeep Gladiator LED Elite Headlights (diodedynamics.com) Hoping this line expands soon to cover our sealed beams.
