I bought this underglow kit and led headlights off amazon. 50 bucks or so for underglow and 13 for the set of off-road lights.
I use 12v batteries that I bought for my daughters Barbie Jeep a while back and stash it in the rear compart under the seat. I still plan on troubleshooting the stock 12v for all the lights but the engine runs just fine for now and it’s nice to have lights when it’s off too.
The led whip flag was about 60 on amazon
The underglow and led whip flag have remotes and do all colors and lots of functions and effects
