I put in some brighter headlight bulbs, but haven't replaced the headlights with LEDs. I did put LED bulbs in both the fog lights and the back up lights. All of those things helped, but the lighting still sucks.
I worry about LED headlights because they don't generate enough heat to melt off snow and ice, and most aftermarket LEDs aren't heated.
Then again, Jeep included LED headlights as an option on the 2017 models, and even they aren't heated.
As much as I love most everything about my Jeep, I have to admit that ALL of the lights on it are worthless.
My rear bumper has cutouts on the tire carrier for rear mounted lights, so at some point I may install some cheapish LED flood lights in the back and wire them up to my back up lights. Even with the LED bulbs in the back up lights, backing into my parking spot at home, at night, is more a game of "it feels like I'm in the right spot" than "Oh hey, I can see what I'm about to back in to".
